As experienced on older models with self-steering tag axles, only three instances would you raise the tag. 1- Making sharp turns at slow speed, 2- When moving in reverse, and 3- Loss of traction / Wheel slip ie; icy road surface. All other times, that tag axle must be on the ground and inflated for stability, weight distribution, and braking. Today's modern coaches/buses have ABS braking which assists with traction control by automatically adjusting air-bag pressure as needed to put more weight on drive-axle for better traction. They also have a reverse switch so when the transmission is placed in reverse, it automatically raises tag-axle to prevent wheel binding from un-commanded steering.
You hi up up hi
Will Prevost ever include a active tag Axle on there current design like Newell ?
At the very end he made a comment about entering a driveway with a slight rise but I'm confused as to whet6her he meant to say lift the tag axle or don't lift it. Our driveway has a slight rise over a culvert then levels out. It's not much but there is a slight rise. So do I lift the tag or leave it down? I will be making as sharp of a turn as I can.
Confused! Lift the tag on tight ends turns to reduce tire wear? Some companies are steerable tags to aid in tighter turns? So loose that on Prevost? What about tire scuff with steerable tags? Pros and cons of both? Please enlighten me or make mew Utube explainging. Thank you.
Wow great video thank you God Bless
I always lift my tag axles on right turns, especially when entering or exiting a highway. What about for left turns?
I live in East Texas and a handicapped Veteran.where is the nearest factory please and Thank You God Bless
Does all tag axle units have this ability??
Why have a tag axle that turns instead having it to left, like the Winnebago diesel 46 footer.
Thank you needed to understand better for snow runner
do they make it automatit?
I saw some of your videos when you were anticipating which mega motor home brand to buy. Looks like you ended up with Provost. What made you choose that brand and what year is it?
After nearly two years of shopping I chose to go with a pre-owned Prevost. I found a 2014 Marathon at the Prevost Stuff show and made the purchase just a few weeks later. I came close to buying a new Foretravel Realm and strongly considered a new Winnebago Grand Tour, but am very happy with my decision. Here's a video that explains why it may make sense to purchase a pre-owned Prevost over a new Class A motorhome. czcams.com/video/YOAjQmP74bE/video.html
my friends prevost tour busses have lift axles they only run them up when empty let’s em run the left lane only 6 wheels in the ground
Very good vehicle s
Informative video ... It's ashamed every thread has the troller.
Good information
Good conversation
No demonstration
Why do some heavy duty buses and trucks have a second front steering axle ? .
I've seen some coaches with a tag axle in front of the drive axle.
I heard that a "tag axle" (mid-lift axle) in front of the drive axle is called "pusher axle" cuz it's pushed by the drive axle otherwise the tag axle "tags" behind the drive axle XD
Yes ,some coaches did have the tags up front.
Andy I envy you. You have my dream job. I love gadgets and I love Prevost. In fact, I drove a charter bus (Prevost) for 12 years because it's the only way I could be close to a Prevost. Sad, I know. I enjoy listening to your knowledge and experiences. When I hit the lottery, I will see you on the road. Keep up the good work.
Thanks Philsy!
What if your tag has a degree the wheels turn then would it be better to raise it or leave it down and just drive?
*So, it is called a tag axle, which helps carry the weight on the larger RV Class A coaches.* Research pays off.
Why not get use a Steering drop axle, lots of Tri axles and quad axles have them. This way you have a great turning radius, no scuffing don't have to lift ju t at all one and done.
...it’s a beautiful thing. U-turns on the SF Embarcadero is possible. That’s in a MCI J45...
Why not a steering tag axle?
I lift the tag for ALL turns. But be aware that lifting your tag axle while applying the brakes will affect your stopping distance. Not necessarily a danger, but you need to be aware of the change in dynamics.
Can you lock that tag for traction on snow or sand?
No it's not powered
What language is Andy speaking?
i tought the tagaxle had a steering function..
Lift in every parking lots, tight turns. Unless you want to replace the tag tires more often.
I understand now
you didnt mention engine mounted to tag axle
Does Prevost offer an Active Steer Tag Axle?
The short answer is, No. The more complicated answer is that I found it really doesn't need one as the drivability of this coach is excellent. I'll be the first to admit that I have a lot of respect for the turning axle found on Newell coaches, but I was surprised that when simply lifting the tag while turning or when in tight parking situations, how well the Prevost handles.
The MCI E had the active steering tag standard, and optional on the J. I love the active steering tag and wish that all coaches had it. That being said, lifting the tag on my Prevost accomplishes the same advantage for turning radius.
Setra has front and rear wheel steering. Really incredible to watch do a U-turn.
Most commercial trucks with tag axels they steer. Why is this not a thing in the RV world? Seem like a pretty obvious thing, especially for the price tags they can have.
Newmar has had passive steer option tag axle since at least 2015. Not sure whether Prevost has made this available. I'm not sure how old Andy's Prevost is, however there are a lot of late 1990s and 2000s Prevost coaches in excellent condition out there, so it is quite possible Andy's was built before rear axle steering, if available on Prevost, was introduced.
What happens if you drive at distance with tag wheel up. Does this cause any type of damage?
I think it does depending on the slope
@Sinclair Jones as for trailers, i dont think marathon builds a trailer.
Why don't you guys just put steerable tags on it and when you put it in reverse to back up it automatically picks it up and you don't have to worry about picking it up on the corners I've had that on my Heavy Haul truck for 10 years already
Did that man just say cheap wrangler?
He said Jeep Wrangler. Lol.
the word lift doesnt seem to mean what it used to >_>
why not steerable tag axle?
IMHO, reliability.
You will always pivot from the same points no mater what your do. You in short saving miles on the tag tire... thats it.
Hallo from luxemburg europ
Just make the tag axle steerable.Problem solved.
first... why is it not a steer axle.. and second... It didn't lift at all xD haha.. it just dropped the hole thing.. still having the third axel planted on the road.
Lift every time you turn is what my company says
You forgot snow. Lifting the tag will give your drive wheels more traction.
Sounds kind of complicated to remember
You need to have a steerable tag like Newell come get with it and a push button to start this is 1919 you’re supposed to be the top of the line
Dont raise in a incline? You want more weight on a axle, lift it
Thats bullshit cus you had those on your erler bus
If you are an RVer and like water toys or fishing boats, Look into Expandacraft, a modular watercraft that stores in small spaces and converts into all sorts of different craft. Oh, and we ship all over the world.
tag axles hold engine weight why would lift axle thats stupid and engine will hit top cowling
It needs to be automatic. Too much to remember
It quickly becomes second nature.
@@TheGadgetGuru like the turn signal?
@@diyoverhauler5432 That's a good comparison. The lever is on the left side and when a tight turn is approaching, simply flip the switch. A beep will remind you if you forgot to lower the wheels.
I don't believe this at all. You may be saving tires but turning shorter no way. Eliminating the drag will make it seem as if it turns shorter,
"The more complicated answer is that I found it really doesn't need one as the drivability of this coach is excellent..."

This is about the most dismissively, non-factual statement I have ever heard on the subject.
Prevost chose, quite deliberately not to put a steering tag on their coaches for one reason only.
It will hurt their profit margin.
The band-aid electronics to "assist" the driver in tag axle situations, is, laughable.
There is absolutely no question that a steering tag is beneficial to ANY make or model of coach, especially at the 45' length.
Listening to this guy, or, even the guy from Prevost makes me feel like I am in kindergarten, as a teenager listening to reasons why mommy says it's best not to ask the teacher anything complicated,
Once you have a steering tag, you'll realize that parking, especially parallel and tight right hand turns in city situations makes all the luxury in a modern coach go out the window if you don't have it, period.
Mark, my opinions are based on driving multiple brands of coaches that include various techniques for the tag axle. As you'll see in my Newell videos, there's no doubt in my mind that Newell's steering axle is a noteworthy feature and it's one that "steers" people to its brand. Why doesn't Prevost offer this feature? That may be a good question for a future video. However, when I produced the Newell series, I hadn't at that time spent any seat time in a Prevost. So far in my 4,500 miles in this bus, I haven't been in an single situation where I felt I needed the steering axle. While I'm not an engineer, I'm to understand it's a complex design and I've come to appreciate the simplicity of many of the features on my Prevost and the solid ride and handling characteristics. During my travels in this Prevost, I've learned that during tight maneuvers, lifting the tag decreases the turning radius just enough to clear common obstacles.
On a related note, visibility is a major part of drivability and a factor in tight cornering. It's my opinion that the Prevost I'm driving provides a higher level of "mirror" visibility than the Newell's I drove. While this can vary based on the height of the driver and the seat position, I can only provide my personal opinion.
In regard to the "kindergarten" statement, please note this is a series for Newbies. I fully understand those who are experienced with maneuvering motorhomes may find this information basic. However, those who find drivability as a concern may appreciate the explanations provided in this video and others in my newbies series.
I will, then consider this forum as one for "Newbies", yet, the information gleaned from your response tells me more than a few things about the author.
Noted.
Mark, I'm curious. What does it tell you about the Author?
Well, for starters, it would appear you like to watch yourself type.
So he answered your question politely but you still have to make a sneering remark. What a pompous ass you are.
