Mike I might be seriously looking at it, but without a price I can’t even really look at it, between restoring the two trucks we have and dad having to take off of work for a year to have heart surgery, not to mention grandpa recently being confined to a wheelchair, we don’t really have the money to buy a new truck right now. But if we had the money the worst we’d do to it is paint it up and put new wheels and tires on it and it’d go right back to being an OTR tractor hauling grandpa’s firetrucks to shows now instead of box trailers. What I’m trying to say is I’m sure there’s others out there who could give this truck a good home they just don’t have the cash right now to buy it, especially since it being so rare is probably gonna drive up the price...

I really hope it goes to a good place though, I hate to see any old truck go to waste. Even parting it out is better than letting it rot away or turning it into scrap metal... especially a historic piece like this! It deserves to be back on the road!

its not gonna go to waste,get parted out or turned to scrap metal

That's a fascinating rig, I like the step frame.  Glad it escaped being scrapped.

This may not be a great idea, but if you can't find any buyers, do you think the Iowa 80 Museum might want it?  I'm guessing they wouldn't give you very much for it,  but it would be sheltered from the elements and in a place where people could view it and appreciate it.  That 4x4 MH would enhance an already excellent truck collection.  

Another option might be to loan it to the museum, and if enough interest in the truck is generated, you might find someone who would pay a favorable price for it.

Are the frame rails one piece or is that a z bracket in there to do the offset?

Tulsa Equipment used to convert trucks using what they called a z bracket to keep the rear frame at standard height for a fifthwheel.

What front axle and transfer case are in it, for that matter what are the specs?

The step frame is alike a B426.

Have been towing for UPS since the 70s and have never saw one offered to the public for sale..All trucks trailers package cars etc are towed or transported to a licensed recycler to be scrapped. A UPS rep is there  to make sure it is carried out...Someone got lucky to get this MH ...I myself started towing for them when they still had F Model Macks and Diamond Reo C/Os...Hope this MH finds a good home....

yes its 4WD,biggest damn transfer case I ever saw.,built for UPS to pull doubles and triples in the mountains

 

The front axle and transfer case were the same ones that go into an off-road RD 4x4, e.g., concrete front-pour.  Likely with different gearing.

I was only telling my brother about this truck a few weeks ago as he was talking about getting a 6x6 something or other but has also thought about a Cruiseliner or Ultraliner

I suggested maybe between a exarmy 6x6 R model and a Cruiseliner he could make something pretty special, even sent him the link to the specs on these and the Australian Army R models ,  same front axle and transfer case  in both I believe 

Anyway he bought a Tatra 6x6 375 hp job from QLD

Goes ok he tells me but I doubt it will ever have the cool factor

I know I’m a couple years late to the conversation, but I thought I would jump in if I could. I am a feeder driver for UPS in Montana where we had three of the MH 4x4’s. I was lucky enough to drive one my first year here at UPS. They were great in the snow, and great for getting over McDonald pass. The downside was they got terrible fuel mileage (3.5-4 mpg) And they were always going through wheel studs and Lugnuts on the steer axle.

We were pulling Rocky Mountain doubles at the time 40ft and a 28 ft pup. We also had standard single axle MH’s Which we used to pull double 40s. As I recall the four-wheel-drive was a little bit longer wheelbase and you couldn’t pull double 40s with it.

As I recall it was a 300 hp engine with a straight five speed transmission. Weed burner exhaust belching black smoke. We would Paul McDonald pass at about 14 mph.

it has always been and still is UPS policy that all vehicles are crashed at the end of service life. They generally spray paint them white then paint a serial number on it, then take before and after photos of them being crushed. The UPS Way. UPS is self insured and I was always told that it was for liability reasons.

I did not realize that there was only 12, and did not appreciate what a rare beast that I got to drive. I feel lucky.
