I picked this up on a lark, might be in over my head. How feasible is this rig with this setup to be mini RV? I'm mainly concerned with the engine and traveling long distances with this monster on the other side of the engine doghouse. I've read a lot about this motor but can't find anything related to the application I'm looking at this for. 1981 RV cutaway, they ordered the motorhome with out the home. It was supposed to be a satellite communications van but I don't think it ever ended up being used for that. I look around for 4x4 vans all the time and have never seen anything remotely like this, not much on the web either. 453 T Detroit Diesel motor MT463 Allison 4-speed automatic The transfer case is gear driven, think it's a Spicer? The undercarriage is all custom, airbags in the rear, haven't identified the axles yet but everything is huge, same with the suspension components, I think I counted the leaf springs stacked 11 deep 4.11 I think the front axle might be a Dana 60, but my mechanic wasn't sure, so I'm not. It's kind of far away and I have only been out there once oh, and it's a dually Anyone have any experience or insight that could give me an honest opinion...huge mistake or brilliant find? This rig is heavy but I can't imagine it's going to push the motor very hard. Any guesses on the MPG I can possibly expect? I really appreciate that people smarter than are often willing to take the time to post. Thanks in advance.
