Last year we sold our 4WD, Quigley, E-350, diesel sportsmobile.
Very fun, high quality built in Fresno but we (couple and one or two dogs) did not use it nearly as much as expected (had hoped to drive the Al-Can etc).
We ended up buying a TrailManor fold up TT (far far more room and creature comforts for short mtb trips to Moab and dry camping in the Rockies w/ solar and two Honda 2000s) that we may park in an ordinary, residential garage and be towed w/ our "everyday Colorado vehicle" (Dodge Durango V6, w/tow package-620#/6200#). For us, our smb was a designated camper and not really an everyday driver (still wonder if a dually sprinter might be a more ideal daytime traveler-tow vehicle w/ more storage, day bed/fold up dinette, and a portable porta potty for a lightweight TT-but unlikely an everyday vehicle).
IMO, there is nothing like getting to your destination, dropping your lightweight TT and going for daytime sojourns or a meal without having to worry about losing your camp spot and repacking everything just to go 5 miles to a store.
