I bought my 2011 Berkshire 390BH last year. We took my buddy and his wife along right before the end of the season here in PA. My buddy is like me and goes a solid 255. The first morning he complained that the air mattress leaked air all night and he had to keep refilling. When I took the coach to Boat n RV by Cabela's, I had them check this problem out. They said they filled it and it was fine the next day, so they didn't perform any maintenance. This year, when I took it out with my parents, we gave up the bedroom for the fold out. Again the air mattress leaked. I'm wondering if the air mattress was really designed for a 255lb person? Is anyone else having this problem?
