Checked the specs on our camper...it's actually almost 25'...it does look puny compared to some of the lovely palaces, but it's big enough for us:) Yes, I am very happy with ours!
Keep in mind the bigger you go, the more work: washing and waxing the exterior (you do want it to look wonderful as long as possible, right???), cleaning the interior. And remember, that big rig needs a lot of room to just sit there, either in a WalMart parking lot (picking up a few items) or in a cg, with all your outside paraphernalia...not all of those folks with the huge, luxury class As sit inside all day...some are outdoors all day, and if gone, at the pool, fishing pier, etc...if they're full-timers, they really need all the size and perks...they LIVE ALL the time in that thing!!
