Recreational Vehicles

I've been thinking about getting a travel trailer for some long trips for my family of 3, plus a small dog.

The Airstreams look open inside, and I like the relatively low dry weight as well as the resale value. The only thing is that new models have gotten extremely expensive.

Are they worth this extra cost, and how easy are they to tow? We are thinking of something along the lines of a Flying Cloud model.
