I purchased a 94 HORIZON a couple of years ago and have put about 20,0000 miles on the beast. I wanted to try it out with a less expensive option before buying a RoadTrek, whiich is what I really wanted. It has been a lot of fun. Too close for more than a couple of weeks for wife, dog and I. Mostly wife and I. We try to stay in state parks because they are interesting, safe, clean, and not crowded even when full. Based on my experience, I would not include a generator, hot water heater, or dedicated shower space, in a new purchase (all different than I thought when a new purchase was an option). We plug in every night and depend on showers and electricity to be part of the hookup, and have not been disappointed.
Comfort in the evenings is the main problem. Nothing close to a recliner and HD TV in a B. And there is no way to really get comfortable. If I could cure this, I would stay on the road permanently.
