This may be a bit off-topic, but when it comes to the discussion of Motor Homes vs Airstream trailers, don't forget that Airstream is Certified GREEN. This was important to us. We toured a whole bunch of Class A's on a 93degree day and damn near died from the fumes ...... we had been camping in a vintage
1957 Airstream Wanderer, and we then decided that we would stick with the Airstream Brand, and bought a 30foot International Serenity, and have lived full time in it since. No fumes, no outgassing. Happy customers.
