Bulging side walls 2008 National Dolphin
Hello all,
Purchased a 36ft 2008 National Dolphin DL35C about a month ago its was in great shape low miles, we brought it from Ohio to Florida, made some changes and update of electronics and flooring. We went on our first outing and found when the sun shines on the drivers side wall back but the bedroom closet and bath area, the wall bows out about an inch , when out of direct sun the wall comes right back to normal, if you run water on the wall when hot it comes right back, there is no delamination going on here it is a thermal issue. Looked back on some previous forums and they reinforced the wall by attaching a 1 1/4 angle iron and screwing it into a wall stud that was made into the wall when it was made, but they said there was a 1 steel tube made into the wall , I have been all over this sidewall and the only metal was on the outer frame of the wall with a very strong magnet. Has anyone delt with this issue before with National I know this was there last year of manufacture, need a fix !!
