I just got back home in Portland, Oregon after a trip down to San Jose, California and back in our new 1989 21' Sunrader. We put a little over 1500 miles on it. It averaged a little over 15 MPG which is not bad considering the mountians in Southern Oregon and Nortern California. It is a V6 with an automatic.
Our other Sunrader is a 1983 21' with a 4 speed and a 4 cylinder engine (22R). On our trip from Portland, Oregon to Mobile, Alabama last year (6000 miles) we averaged a little over 17 MPG.
