We have stayed in state parks with our 42' coach and some are fine. Some are not so fine. Ft Stevens in OR has many sites that you will fit in and some sites claim to handle your 40 ft but are a 90 degree turn into the site with a sign right at the corner you are trying to get around. If the fellow across the street has his vehicle parked in the road at all you will be many minutes getting into the site. Also, Maryhill State Park in WA is a beautiful place but the sites there are also very difficult to get into with your size coach.
