I have a 2012 Airstream Avenue built on a 2011 Chevrolet Express 3500. I liked the wide body of the Pleasure Way but not the short wheel base of the Ford. The Airstream has some extras not available on the Pleasure Way or Road Trek that add weight, so this may not be completely applicable. The Chevy has a GVWR of 9600 lbs. and the Airstream fully loaded with supplies full water and propane weighs 9000 lbs. The front axle GAWR is 4300 lbs. and the axle weight is 3900 lbs. The rear axle GAWR is 6084 lbs. and the axle weight is 5100 lbs.
