DH and I bought a tiny Coachmen TT as a way of having a place for our two kids and us to stay when we visited our middle child, a handicapped son, who lives 4 hours away from us. It also gave us and our other two kids a way to enjoy beach and mountain trips that we couldn't otherwise afford.
Over the years, we've had several TTs, a 5ver, even a PUP. Now that it's just the two of us, we again have a tiny, very inexpensive TT that we keep in the town where our handicapped son lives to use as a "hotel" room when we visit him. We've recently purchased an Aliner Ranger 15 to use for actual camping trips - again, a great way to enjoy places we otherwise wouldn't be able to afford!
