I’ve been following this thread, which asks a common but unfortunately subjective question. There are folks happily full-timing in Class B’s while others in 40’ Class A’s lament not having enough space. When I began full timing just over three years ago I purchased a 33’ Class A, basing my needed space decision on a two year period in college when I lived in a beat-up 1950’s vintage 8’X25’ travel trailer. It turned out that for my needs my 33’ Class A is too big. Half ways through my first road trip, a 6,000 mile loop from Texas to LA and then up the west coast to Port Angeles WA and back to Texas via Denver, I began referring to my RV as “The Behemoth” and the name was not meant as a compliment! I’ve since made modifications to the suspension, replaced the engine, installed exhaust headers (more power) and I’m liking my palatial manor much better, though I still wish it were shorter, not over 30’. However that’s just me, your size needs, both actual and psychological, may vary. As it is I’ve developed a work-around that suits my full-timing needs. I typically stay at places for a month at a time and use my Class A as a home base. I use my toad, a Dodge Caravan and a 250cc dirt bike, to further explore the area I’m visiting.
Of all the advice you've gotten in my opinion 2gypsies advice stands out as the most useful, though I’d never go with a 40’ RV like they did. But as I said, it’s all subjective.
