So you are going to buy your first Tavel Trailer

I agree it is hard to define Superior because it is mostly opinion.

Some consider Airstream, the various Casita or Bigfoot shell constructions, the four season models and a few other brands to be a cut above the rest. Hence they command a premium dollar for their size.

Interestingly enough my DW did not care for such features. Good old stick and tin was just fine for us. :)
