Having had every conceivable type of RV over the years. some of my best memories were in a truck & camper. I've gotten stuck on every beach in Mexico, and camped in beautiful places in the US that you could only dream of seeing in anything other than a good 4WD truck with a camper.
I think the answer whether full-timing could work in a camper depends on what kind of RV'r you are. To some, an RV is a place to sleep and cook, and being outside as often as possible is the goal. To others, the "all the comforts of home" on the road is most attractive. From your comment that "I just can't see sittin inside all the time" it sounds like your part of the first group, and as such, I'll bet you could have a ball in a well-outfitted camper.
Sue and I camped next to a professional Bass Fisherman a couple of months back who lives full time with his wife in an 11 1/2' Lance on a Chevy 1ton pulling his bass boat. The camper had a Directv satellite, 4KW generator, solar panels everywhere, triple awnings, electric jacks, and a lot more. He wasn't giving up much by going the truck/camper route.
