Sue you shouldn't feel that you hijacked the forum. This is what it is designed to do, share valuable information to assist each other.
I have owned 2 custom camper vans, 2 towables, a class C and class A diesel motor home before purchasing our Mobile Suites. With each purchase, the quality has declined while the prices continued to rise. I sincerely believe in buying made in America but the quality of today's goods and services has declined over the years. (in my opinion) From what I have heard, DRV products have followed the same path. I had 3 pages of things to be fixed and it took 2.5 weeks in Indiana to get everything fixed. Having said that, I still believe that DRV products are the best on the market. Yes, I had problems but they were all fixed.
It also helps to have a good dealer. I shopped several dealers before picking International RV World. Dave Titus has been excellent to work with and extremely knowledgeable of the unit. I'm sure there are other great dealers as well along with some terrible ones.
Finding good repair centers can be a challenge as well. Paul & Kay Cross at Indiana Interstate in Lagrange, IN does great work. Don & Brandy at Land Yachts in Jupiter, Fl is another great repair shop.
Flexing frames - From my experience, flexing frames typically come from overloading the unit.
Lastly, ask repair shops that do not sell RV's to rate manufacturers. I did this for motor homes and Newmar and Tiffin were number one, hands down.
