Let's hear it for the Bambi!
We absolutely LOVE our 19' Safari Bambi - it's perfect for us. The bed is very comfortable (of course we upgraded from a VW Eurovan pop-top camper!) My husband has always had boats, so we have never had a problem backing up our Bambi, and she tows effortlessly. If you do decide on the 19' be sure and get the wrap-around windows. They make the whole interior open up and feel quite spacious. We have had 4 adults around the dinette for dinner and was very adequate. Room with a view! Good luck - either size, you can't lose with an Airstream. It was certainly our dream come true. P.S. we are getting ready for a trip to Idaho right after Labor Day. Going through Oregon, Washington.
"We find that after years of struggle that we do not take a trip; a trip takes us. . . Only when this is recognized can the blown-in-the-glass bum relax and go along with it." ~John Steinbeck, Travels with Charley, in Search of America
