Well he did say "what is the best". The best is an Airstream. Used to work on all kinds of travel trailers at the RV shop we owned. Worked on very few Airstreams. I wouldn't want one by any stretch. Not my kind of trailer, but they are built to very high standards and like everyone has said, very high cost. I think if you were to say what is the best "normal conventional trailer" if there is such a thing.........likely a Bigfoot, they seem to be close to conventional design(not a bubble)and are priced like they did it all correctly. Thing is, they cost like 20k more than my Creekside and I can do a lot of correcting and upgrading for that kink of cash.
