Is there a high end TT other than Airstream?

I know and understand that an Airstream is really not built any better than most other RV brands. What I am looking for is to simplify our camping experience. We pulled into a rv park last night where I was assured they had a site that would fit us. They didn't so even though I was very tired from a 7 hr. drive I had to unhook and drop the trailer before I could set up. With the 40' coach and 18' trailer, I have to plan and research where we are going to go and stay. I want something smaller and much more maneuverable. A 5er is still a bit on the large side for my intentions. The appeal of the Airstream is not only the unique design but also structural stability of that shape with no slides. They all need repairs and maintenance but fortunately I'm very handy at all things required. We are at a crossroads with camping right now. Kids are 17 and 15 and soon will not want to go at all. We are 10 years away from retiring and if we keep this coach it will be worn out by that time.
First world problems!
