Bought a Freightliner MT55 that was used as a state DWI checkpoint. It has the Morgan Olson body and converted by Farber.
This thing is built for stout. I don't understand why more conversions for RV aren't done on this platform. Well, there might be one. Ear plugs wouldn't be out of place at the front. It's not bad, but there is more noise than one would expect. The other would be the engine, a Cummins 5.9. She is a tough one but a little on the low side for HP. A cummins 8.3 or similar would be nice
. The gearing is nice though, 65 mph is right at 1900 rpm. Just not enough umph.
It has the Allison 2000 tranny. This does not have the parking pawl. So when you park it you pull the parking brake. When shifting the selector you don't put it all the way to the top as you would a vehicle in park, cause that is reverse! Only took me a couple times to remember this one, the backward movement got my attention quick.
I have the electrical schematics. Without those this thing would be a nightmare. There are so many wires. After looking at this I understand why people have so many problems with their electrical. Loose wires everywhere. Stuffed here and there or out of sight out of mind. People need to understand as these get older the wiring gets brittle. I've been doing a lot of zip tying. But this '03 looks like it still has the original electrical equipment and a/c's so I figure it is planned pretty well. 70k miles on the rig which is not a lot.
Has one heck of a generator, an Onan 12.5 Kw with the Kubota 3 cyl engine. Consumption is supposed to be .1 gph at idle, 1.2 at full load.
So I've been going through regrounding all the wiring that is corroded and taking care of maintenance things.
Parts are still available for the most part. The aluminum body is heavy stuff. Not the flimsy stuff I expected. From the diagram, the roof and sides are insulated with 3" insulation. Over the scale weight was 19k lbs. at the dump. Still need to take it to the truck scales to find rear/front weights.
One other thing, the zinc plated fasteners don't stand up to the corrosion very well, they corrode then break. I'm in the process of changing out zinc plated stuff for stainless. If you put a stainless screw through the aluminum you better make sure it is the right size hole, the aluminum is thick enough it will break the screw, and I've been using anti-seize on these installs.
Oh, and one other other thing, no fiberglass
. The roof is one piece front to back aluminum.
