What did you do??

I have a Rockwood pop-up camper and am moving forward upgrading the AGM deep-cycle battery for a 200 W Lithium. Your video information and installation is very helpful and I am glad you brought up the point of charging the Lithium battery from the car with the current wiring setup is not the efficient way to do so, hence the dc-dc charger you suggested to use. Could you provide more information on the 8AWG wire you used? Where did you order from? Part number? I am going to research locally who may carry something similar. There is an industrial electrical supplier that may or must all sort of options for the wire. Thank you for the details and easy to follow steps. Great job. Kind regards, Otto.

A great video!!! My converter in my 2015 TAB S Max just died. I contacted the TAB NuCamp company, and they said they are currently putting in the WF-8735-AD in their TAB 320's. It was so helpful to read these comments on the importance of specifying the newer "firmware" in the power center you upgrade to. I want to make sure I get the newer V.19 (or possibly even the V.20??) firmware in the power center I purchase. Now that the latest version of the firmware is available (the V.20), would that be the best one to get? I still have a lead acid battery in my 2015 TAB S Max but would really like to change over to lithium at some point. Would the V.20 firmware then be best? Is the company you ordered your power center from able to determine which firmware version they send out when you place your order?

What a great video! The converter in my 2015 TAB S Max trailer just stopped working. It is the "WFCO Model WF-8735P". I plan to replace the entire power center as the easiest route. What I am trying to determine is what power center to use as a replacement, as I would like to convert my current lead acid battery to lithium batteries in the near future. In your opinion, what is the current best model power center to replace with (it is now 2024) when planning to convert to lithium batteries in the future? (Would the replacement of choice still allow me to use my lead acid battery until I do convert to lithium. Otherwise, if there is now a clear choice designed specifically for lithium batteries, I could probably switch to lithium now instead of waiting.) Any thoughts would be appreciated so much.

This is my exact shower door and this was the problem I was having!! Thank you so much for the clear instructions on how to fix this.

What if you were to simply pull the incoming line, or put a tee there with a ball valve, to the reservoir - The run the pump while you keep the reservoir filled and simply push fresh fluid through?

You love this thing, but have you spent the night in there with the fanny and what do you think of that please give us an update

Oh, my goodness thank you for taking time to make this video. This explains everything in such a clear manner. I think you just solved my problem….. A like doesn’t seem like enough gratitude but it is all I can do.

I just bought a cute 2015 TAB 320S (Max S). My shower drain is in the middle of the shower pan instead of off to the left corner, for some reason. I checked that screw in my shower drain and, sure enough, it was an old rusted wood screw just like yours! Maybe that's what TAB was using at that time?? So, I'll have to find a stainless screw. I don't feel any flex in my plastic shower pan floor, so hopefully it won't need the foam reinforcement repair for now. Thanks for such a great video!!

That’s a great spice rack! Love the engineering!

As good as the Victron unit is it could be made better if they modified the “To Battery Minus” side to fit directly over the negative terminal of the battery with the standard battery screw.

I needed some place to store a laptop or full size ipad while traveling. Had my brother-in-law purchase some scrap aluminum that we bent to form a low profile shelf. We bent each side 90 degrees to form an L so we could attach it to the bottom of the table. We added a small strip of aluminum to the back of the shelf for added security. The opening faces the driver's side of the t@b. It is wide enough for a full size macbook pro and a ipad mini. Never have either fell out and we've been on some rough roads. We pull a 2019 t@b 400 bdl

We pull a t@b 400 BDL (2019) and never had an issue with the tow vehicle (Jeep Grand Cherokees) providing power via the 7-pin. There was always power to charge the batteries (ACM and later lithium) which powered our fridge (DC/AC/Propane). Got a new tow - 2020 Ford F150 5.0 and immediately began having power issues. After lots of research and reviewing forum chats, we learned the new Fords only provide enough power through the 7-pin to power the side camper lights. Won't power the Furrion rear camera and it was wired to the rear lights. Everyone said we needed a DC to DC charger. I didn't feel comfortable doing it but my son is one heck of a mechanic/electrician so I purchased everything and one Saturday we tackled the problem. We began at the tow battery running a heavy gauge wire with a fuse, from the battery to the rear bumper. We also attached a heavy duty on/off switch close to the battery. We connected a Harris plug and attached it under the bumper as close to the 7-pin connector as we could. Installed the DC to DC inside the storage container on the front of the t@b. There is a junction box under the front of the t@b that was easily accessible for wiring from the DC to DC and we ran wire from here along the normal 7-pin wire to with another Harris connector to attach to the tow. Works great now - when connecting I hear the DC to DC start up and confirm operation by looking for the green light. Easily handles the charge of our lithium batteries. Now, one other issue with the Ford we discovered on some of our early trips. After driving for several hours (pulling our t@b), we might experience a hard start after a stop, when turning the tow back on. Initially thought it was a battery/alternator issue but testing both showed they were performing perfectly. More research and we learned Fords, under towing, are known to suffer from heat soak. Meaning, the starters get very hot due to their location near the manifolds. The solution is to wrap the starter with a heat shield. Cost about $20 on Amazon, came with two wire flex ties to secure it. Since installed, the hard start issues have gone away.

We have a t@b 400 and travel around 200 days of the year with it. Have to simple (for us methods) to level our t@b quickly when pulling or backing into a site. First, I use LevelMate Pro. I have it installed in our t@b and connect to it via bluetooth and the app on my Iphone. I can tell very quickly if I'm level East to West; at this point I don't care if I"m level North to South. I then verify what the app is telling me by looking at a small level installed under the front window of the t@b. I have four easily accessible rubber blocks (much like lego blocks) that we can quickly set behind/in front of the trailer wheels. I think in all our travels, only once have I had to double stack leveling blocks.

Great video thanks for sharing. I have a WFCO WF-8735-P and was thinking this would charge well enough Lithium and then my 480w solar would bulk charge or top off the rest. Think that plan would work?

Yes, If the ambient temperature is higher than can be set on the thermostat, the furnace pump will not cycle on.

I got one side all done, fixing all the corrosion and using the magic paint on the connections and adding a low point drain. The system was working great, until I had a break on the other side of the camper where the Alde system is (with the rubber t drain) due to a corroded connection. I fixed that side and put in new fluid. Then I tried to run the pump to get the air out but the pump would not run. I'm thinking it is because it's too hot inside the camper (we're in the hot sun of FL) for Alde to turn the heat on. I'm going to try it again when it cools off. Have you experienced this, that is the pump not running due to the temp inside the camper?

So helpful! We just bought a 2015 320s and our learning curve is proving to be quite steep. Your videos are clear, easy to follow, and so very helpful!!

Did you do a video on setting up the auto detect for lithium batteries? There's a process for getting the audio detect to recognize the lithium. Green lights next to the fuses is for lead acid, blue lights are for lithium batteries. I just installed mine and ready to set up for lithium. Please let me know if you have a minute. Thank you

Great video! Thank you. Since the only apparent difference between the 8735-P, the 8735-AD and the 8740-AD is the converter, could you have left all of your original 8735-P hardware in place including all the breakers, AC connections, DC connections and fuses, and just swap out the converter? If not what is the issue that negates this theory. Thanks again

Hi Great video series, thank you. I have a question about the wiring. I have a GMC Sierra 2500HD with a 6.6 Diesel and it has two batteries. Do I connect the wires to both batteries somehow, or to just one. Please advise. Thank you. Hope all is well.

Another good idea. I happen to have just bought a tin of old fashioned beeswax. Do you think it would work as well ? Also, I like your table upgrade from the laminate original. I replaced mine w a nice piece of walnut butcherblock - which eventually deteriorated in the elements. Now, mine is 1.5 inch thick Azek- bombproof.

This was a very informative and well done video. I’ve owned my T@B 5 years now and I think knowing my hot, cold and bypass lines helped me understand it. I’m a 72 year old woman and I definitely learned more about winterizing. I live in the south in a hot climate and don’t have to winterize every winter, but I sure like your method of not having to deal with de-winterizing.

Thanks so much for this series. I was waffling about whether to try this myself or having it done for me. Yours is the first that actually explained the whole process succinctly yet thoroughly enough for me to understand

Instead of making a drain out of soldered copper pipe and a tee, could you use pex and sharkbite connectors to make the drain?

Thanks for this idea. I found a big rat in my battery box today. Peed all over it and everything. Gross.

The copper T I got is the correct size you specify, but I notice the fit into the hose is tight. Is this OK? It seems that the 3/4 inch copper pipe I got is a better fit. Would it be better to solder two pieces of 3/4 pipe into both sides of the T and then connect the rubber hose to these pipes, instead of just using the T. Is a slightly tight fit OK? Is it possible that my copper T is a bit thicker than the one you used? Are they standard?

You are fantastic! I've learned a lot from you. I have the exact same T@B camper (same year too). I'm working on my connector corrosion problem using all the suggestions you mentioned, including using the magic paint. I'm getting ready now to reinstall all the radiators and hoses. I had to cut back some of the ends of my radiators because of extreme corrosion. I removed a few fins and my radiators are slightly shorter, but I think it will all work out. I haven't built the new drains yet, but that's next. Now, I'm a bit worried about refilling the system and getting the air our, so this video is really helpful. Your drawing of the system is also helpful, showing how all the hoses are connected. Thank you!

Mark, Is your T@B a 320S? I have a T@B 400, do you know where the low points are in my trailer? Why couldn t you install vales in the new drain points inside the trailer? You can mount the valves horizontally to the side and the fluid will drain completely because when the fluid drops to the top of the drain, a small air gap will form allowing the entire volume to discharge. The value eliminates the exterior cap that could be damaged and leak withiut alerting the dangerious consition to the pump.

With the newer tabs having the connection in the nautilus compartment would you make it longer?

Thank you very much! I just came to Home Depot to get me a Multimeter Reader. Im going to troubleshoot some electrical issues I got with my TAB 400

Just watched and made my own checklist to winterize today. Thank you! This is a much. nicer approach over antifreeze for me. While the video is long, I appreciate the 'why' behind all of the steps as it helps me grasp the whole concept. Thank you.

I want to change my glycol and change the automatic air purge valve. if I drain the fluid from the extension bowl through the drain under the trailer, then I disconnect the hose that runs from the bowl and send air from that hose to empty the rest of the fluid from the system, does that will air pass through the pump, or stop at the pump? I have had my fluid in the system for 6 years and it doesn't seem to have any corrosion like in your video.

Well I know you've heard it, but I JUST finished clearing my water lines in my 2018 Tab 320 using your method. Great! I had drained earlier and thought I'd gotten all the water out, nope! Great system, made notes, thank you!!

Thank you for your informative video. I just purchased a 2010 T@B by Dutchmen. I have 2 water discharge capped spouts located drivers side in front of the wheel. I can figure out your blowout method, however, do you know exactly how these two spouts operate? There is no information in the owner’s manual. I still need to get the excess water out of the water lines. I do not have a bathroom or hot water tank in my T@B. Any help you can provide will be most helpful. I can send a photo of my water system. My thanks for the info you already supplied. I’m new at Teardrop camping. Thank you, Lynn

Any follow-up how it worked? I'm having the same problem with the same kind of box, though mine are for solar power in a detached shed. Went to bring the batteries in the house to test and perform maintenance and discovered nesting in them.

That's a simple and very effective cover you have made. Do you anchor the front legs when you have the roof in the down position. It strikes me that without being fastened down a wind could catch the front roof, lift it and potentially cause you some grief.

Omg what have I purchased. I do not have the skills to do this 😢

Crazy that NuCamp didn’t figure this out

What a pain in the butt. I have to figure out which I have in my new 23 320

Since there are two lines on each side, why don’t you have to put drains in all of them? With just two, one on each side, how do you remove the fluid from the other hoses?

Alde are absolute insistant that copper fittings MUST NOT BE USED in Alde instalations. This is because copper reacts with the metals used in the system and WILL cause corrosion.

Thank you. Your video made the unknown know. An important topic for the safety of my family.

I need a whole new kit. Where do i find one?

That was the best video. So understandable! Thank you

Truly appreciate you man ...Thank YOU

Any issues with CMP on my 2020 320s? My co2 alarm keeps going off in the middle of the night, even when my Alde is turned off.

After reading all of these post about the WFCO AD models, it seems to me that they are a lot of issues when trying to use them with Lithium batteries . Seems like the AD doesn't work the way it's supposed to. I've been researching CZcams and its looks like the best things to do is to switch over to 'Progressive Dynamic' converter which has a switch which you can set for the type of battery you have or about to change to, like me...I'm going with the latter..Progressive Dynamic....Less headaches..But thanks for the video on the installation guide and tips..

Hi. Great video thank you. I followed this method for my 2018 T@B 320S, with the added step of also doing the outside shower, which I'm assuming is not a part of the particular model in the video. Did all the steps at different levels of camper tilt as a trial with a bit more water being blown out. Am a bit hesitant to leave the covers off the sewer pipes with lots of critters locally.

Hello! Thank you for the video. I have a different sort of problem--I left behind my stabilizer jack at a campground during a trip a couple of months ago. I have called NuCamp and my local T@B dealer to no end. The local dealer was no help at all! Can you help me? My T@B is a 2016 320S
