I'm running one of the smallest FWC campers they've ever made and I can't see me taking mine out for more than a couple of weeks at a time. But I can see if a guy, his girl and a dog are going to full time it needing to have more of the "comforts of home" than I have. Yes it's 3 times the size of mine. He won't be following me on some of the trails I take mine over by the reason of the size of his truck alone. But he's not just going out to go wheeling. It's basecamp for all his other activities. Camping out at a Ski Resort or on a beach in Mexico might require the need for 4wd to get there.
In this hobby there are more posers than not. That's a proven fact. I've got half the gear of some of those guys and sure surprised the hell out of them when my old squarebody rumbles up to the same spot they are in. I find it funny some go nuts on the gear and never actually use it. But if that's what somebody wants to do with their money who am I to question it.
