rusting out cargo bins

I read the "4 Questions" promotional piece put out by Winnebago and my first reaction is to want to go out and buy a new Winnebago RV. I'm surprised by some of the posts here especially indicating a lack of quality in the structural steel and how it is primed. Also, as I look at a particular Winnebago line and study it carefully, my preliminary analysis is that the fit and finish of their "lower end" RVs is marginal. For example, the shower is not a 1 piece fiberglass shower stall. It is thin cheap panels glued on the wall. Posts like these scare me away from the Winnebago dealership. I really wish these problems didn't exist because they are close to me and it sure would be a convenient place to do business. Winnebago overall has an owner satisfaction rating in the 70's (RV consumer group ) perhaps in part due to this rust problem. Todd in Minnesota. (Planning to order a new RV in 18-24 months)
