Good content. Thank you for bringing these issues to the fourfront and making me think. I just watched "Chasing the Dogs" video of the same event. You can fill the air tank externally to release the brakes (from portable electric pump or form another truck (Mog etc). Anyway, that's an interesting situation that I had not considered with a unimog. Air Actuated brakes over hydraulic, and Fuel supply on extreme angles with less that full fuel tank(s). Possible solution. Have have a second fuel tank and I'm thinking look at a pickup at the front left on one tank and at the rear right of the second one. Then consider that if tanks are low and you wind up in that situation again, switch to the appropriate fuel tank. Also try not to use the winch on low battery, its really hard on electric motors to run them hard at low voltage. They can (seamingly paradoxically) burn out very easy due to low voltage... been there done that!
From memory you can bash the back brakes off with a hammer in emergencies. You just bash the arm with a hammer and it releases provided you dont mind having no brakes at all. If you are planning on traveling with other MOGs id be carrying a 20m air hose and some fittings so you can piggyback truck together if needed.
What good fun and learning. Only thing I could think of trying would be to, if possible, disconnect the fuel line at the tank and put the line directly into a Jerry can. Maybe you could strap the can to the passenger steps. Also, does the truck normally lose air pressure that quickly when turned off?
They're not supposed to lose air that quickly but they're around 30 years old, air pipes going everywhere, and it's tough to trace all the air leakage. The fuel suggestion, if we did not have other mogs for a pull, is definitely the solution.
So did you manage to eventually unlock the rear brakes, or did you skull-drag it up with them still locked on? I've read that they can be prised off in an emergency, but haven't seen it done
Tank had 3/4 full of fuel, the incline is a lot steeper than the video shows , I would guess that my prepump is worn and not pumping properly , just don't notice on lesser inclines
I have a u5000 that i got in non running condition, your vids are inspiring me to try rebuild it. Your stuck friend said it, great content!

Another great video Thabo.

Please add comments, it helps with the algorithm.
I need a unimog. Mission for 2024.
Not going to lie. Most of the recovery gear you are using is way under rated for a 7-8 ton truck.
The best approach for winching double line pull saves winch and batt.
As for starting ether (starting fluid).
Great video

@@ThaboNelmeanshappiness No judgement here, just curious - agreed, finding leaks is not easy.
All of that logging is plantation likely planted in the 1970s.

Great Stuff.
Nice VIDs.

next time fill up the tank didnt relise they starve for fuel electric fuel pump needed ?
Add a battery powered tyre inflator to your kit.
Release the brakes by pumping air into the tanks via the gladhands. Either with your truck or with an aircompressor
We were thinking of that but then managed to release the brakes by knocking pins out with a hammer.

We discovered that pins can be knocked out with a hammer to release the rear brakes.
What exactly went wrong with it? I assume empty tank and it sloshed away from the pickup? Then why couldn't they start it when topped up?

the video is good, but I would like less music, it’s better to listen to the real sound of the engine
