Well, it has been a dream for 20+ years and I am perhaps (foolishly?) about to make the plunge. Old Mack RS700. Pure mad dog. While the thing will be part RV, the remainder will be used as a combo school/shop going to disaster sites teaching/performing engine and heavy electrical repair for red cross, samaritans purse, etc.
This truck has very heavy specs 14K ft/44K rears camelback suspension. A typical RV or van box wont survive that suspension or anticipated environments I plan to take it into. Large diesel mechanic and DC electrician I am...carpenter and RV savy? nope.
Want it minimalist inside like a WWII Navy ship "crew quarters" 2 bunks, head, shower, small galley and desk is about it. It will have a 3-71 Detroit genset for "hotel" power hanging on the frame rails. Comfort and quiet? Absolutely not.
Would welcome anyone that has suggestions on making a 20' conex into a combo living quarters/shop and making a pass thru from an old mack cab into the conex. This thing has got to be able to "go anywhere" and survive hail, floods, heat, cold, tornadoes, etc.
