Hi I'm new to these forums and I couldn't find any threads for body work, but I'm just wonder if anyone has any rust forming on there box on 2008 silverado/gmc? My truck is a quad cab, and I can't find anyone who has this problem. Now I'm thinking that it may have been in an accident and obviously they did not repair it properly. This truck has only 93000km, and I live in Ontario Canada, where there is lots of salt, but still I know a lot of people with the same year and they don't have rust. Any responds is appreciated. - - - Updated - - - I also would like to add that there is no rust anywhere else, not even on the other side of the box.
