I will add my 2cents here take it for what it is worth. The experiance I have is with a previous gas motorhome. 36'. They try to make these things as acceptable as a diesel coach and some do. However a lot of these coaches are weak in the frame area. Thus twisting occures and stuff happens. I have not had a windshield come out but I really notice the differance in the frame support. I have had three gas coaches and two diesel coaches and they are built differently. They were all quality coaches per my perception. Some of these lower priced coaches are just that. Check them out.
