View Full Version : Finally bought a U500
Third times the charm. Rob Pickering picked up a U500 for me at auction today. I shall be with mog in a few days.
And thank you PG&E customers for a truck with 2300 miles at a bit more than 1/3 sticker.
I must now learn to repair a 200 pound de-beaded tire. Where do I get a five foot torque wrench?

I looked really hard on the Internet and finally found one (0-600 ft-lb) for $300.

what do the U500 lugs torque at?
Is anti-seize worth using?
Is there enough air to use an air tool?
thanks
Oh Charlie, did you ever write up using a bike inner tube to reset the bead?

What are you going to do with the cement mixer?

Is anti-seize worth using? Maybe???

Congratulations, dzzz! Keep us posted about your plans for
your new 9900 lb, portal axle equipped toy!

It's owned by Rob Pickering. I assume he's going to sell it.

Thanks, I wish it was 9900lbs. With the bed I believe it's 16,700. I don't know what the cab chassis weighs. Almost all of the U500 in this country are 33,000 GVWR. I didn't really appreciate the high GVWR until I started to run the numbers. It allows the capability to carry the heavy liquids to stay out without resupply: beer, water and fuel. I really like that I can consider 200 gallons each of water and fuel while keeping the GVW under max.
Every other option I look at was weight constrained. The U500 is volume constrained. Actually this constraint would make a hard sided popup the best choice. I just don't know if I want to add that complexity to the build time.
From what I've seen a hard sided popup with the bed is above the kitchen is a considerably bigger camper than a standard camper at the same length.
Anyone with a larger camper please add what has worked well and what you would change.
Speaking of Rob Pickering he has an unsold 1017A cab chassis, at least as of a few weeks ago. He also has a sold 1017A that is painted desert tan. It looks exactly like what one should be driving around North Africa. Not sure of the chassis length, but definitely long enough for a nice camper.

CONGRATULATIONS!!!! :wings:
You are now officially envied.
Re: wheel removal and attachment . . . . on Camper Mog I had a five-foot cheater bar strapped to the rear bumper that slipped over a one-inch drive breaker bar with the correct six point socket. My math talents then came into play to figure out how far out on the bar to stand to supply the correct amount torque. Crude but (theoretically, at least) accurate.
However, before going anywhere significant, it might pay make sure all of the lug nuts/bolts will come off with your breaker bar or torque wrench. One at a time, try to loosen and then retorque each one. On Camper Mog, this went fine for three wheels, but some on the fourth wheel just would not break loose. Ended up going to the big truck tire place and prevailing on them to use their impact wrench. The guy started with a tool two sizes smaller than he ended up with, but eventually broke the bolts loose, and all was well everafter.

Yeah, Ditto, Jealous!
I too have thought about the concept of the loft bed. I think it would work really well on a Mog. Lots of room to really enjoy the area without taking up space with a bed that is otherwise useless during the day time.
Waiting for photos! :)

:peepwall:
The story is that they used the truck instead of a helicopter to deliver concrete. I'm still looking for the hover button........

Don't know if Harbor Freight is still selling their gasoline powered impact wrench but I got one for $87. It does about 1200 ft lbs of torque. That impact wrench and the correct torque stick should work.

Install on-board air and use one of these.

Whoa! Consumes 58cfm at max load?! That's a heckuva on-board air system.

Get that beast home yet???
BTW - You can tap the onboard air system to run air tools. Not 50+ CFM but it will run more than my home compressor.
Figure out what that thing in the middle console was yet??

According to Unimog NA's weight spreadsheet my cab-chassis weighed 3800kg front/2400kg rear. Since it's now 4350 front and up to 8500 rear, that's a useful payload of 6650kg = 14663 lb.
The rear axle is actually plated at 9000kg and the tires can be overloaded to 12300 lb:
