Don't know where you are but if the SD in your signature indicates South Dakota then you may not be too far from Denver. I recommend Diversified Truck & RV Repair. They work on commercial fleet vehicles and RVs and I have had dealings with them for many years when I managed a fleet repair shop. They also replaced the roof on my 5th wheel after an incident with a tree limb. I recently spoke to them about an issue with one of my slides and the staff explained about the work they have done in that area, including a major rebuild on a slide of a brand that is out of business. I have always found their work to be first rate.
