OP, pic 2.  Some of these used the front wheel drive system or many components from the OLD's Toronado.  Is this one of them?  Just my brothers opinion, "Never buy an RV with an engine, always consider one you tow".  SBJ, there is a plethora of YouTube vids try "nomadic fanatic" while I doubt everything he says is doctrine, it will bring up tons of these vids, discussions.  Things I never would of thought of,  Jump up and down looking for weak floors,  water leaks are common on the front end cap and often hidden by built in cabinetry.  My dad would say "for what these cost you can spend many a night in a hotel".   I think that may not be as  true now days.  Nasty bedspreads/linens, bed bugs, poor security. 

All good points vacerator,  I think my brother was looking at it from the standpoint of using the tow vehicle for his work and farm as opposed to tying up money in something that only does one thing.   The separate truck qualifies for tax deductions when used for farming or business.
