I'm at the opposite end of the spectrum but thought I'd give my 2 cents. We have a 37' TT with a suble single, large slide. Having used a 23' for years we decided to go big. We have two kids with another on the way so we wanted much more space. The 23' (with slide) always felt cramped to me. We've stayed at numerous parks (just pulled in from a trip a couple of hours ago) and have never had a problem with the length of our trailer in regards to camp sites. I admit it's slightly more difficult to maneuver in small spaces but personally that's a trade off I'll take. As someone mentioned earlier, get stuck inside on a rainy day and 23' or so gets cramped (even for just 2 people). I'd recommend a 25-30' camper without the bunks. I found several when we were looking with nice living areas (recliners, large viewing windows, etc.). I think that range is kinda the best of both worlds.....big enough to allow some space but not too big/heavy. Good luck on your decision.
