All great posts, and they show it all boils down to personal preference and what you like to do when you camp. We have a small 17' tt we've used for 4 years now. We love it and plan to hang onto it until retirement. At that time we plan to do a lot more camping with trips that are much longer. Right now our longest trips are two weeks long. Most of the time it's just the two of us, but sometimes one of our older(20 something) kids join us.
What we like is the camper has everything we need. It's light, easy to pull, and we get into any site available. The small size kind of "forces" us to do what we love....spend time outdoors.
What we would want in a new camper includes a couch of some sort so we don't have to sit at the dinette all the time, a bed that has access on both sides (my wife complains every time the bed is made) and lose the "pinch point" between the kitchen and the bathroom wall.
As far as being stuck inside the trailer for three days, I can't take being stuck in a 3000 sq ft house, the trailer would kill me! Our trips always include site seeing and visiting, so for us that's not an issue.
Good luck and have fun!
