Welcome to the world of RV warranties. You mentioned Bozeman Ford but unless I missed something you didn't mention the dealer in Utah.
I had a warranty problem with my Monaco MH. Monaco rep sent me to a Salt Lake Ford dealer for repairs. They worked on it for over an hour and said they just didn't have the equipment to do the repairs. (suppected the fuel tank had to be removed) Monaco told me if there was any charge by the Ford dealer they would re-imburse me. The Ford dealer told me no charge and helped me find directions to Motorsportsland. We were treated very well and they repaired the problem within a few hours. Neither of those dealers even sold Monaco MHs.
The reason many dealers don't want to handle the warranty issues is many RV manufacturers are really cheap. They don't want to pay for warranty repairs. They discount the warranty repairs. I can understand why dealers don't want to handle those repairs unless the RV was purchased from them. There are a few RV manufacturers that will step up to the plate and pay the going rate for warranty repairs. Since Monaco owners got beat up pretty bad in the past I think Navistarrv is trying to build up the name again by paying for the warranty repairs at the going repair rate. All 3 of my warranty issues have been handled at dealers that never sold Monaco MHs. They were glad to get the business. How long this great warranty service will last, I suspect, will be based on if Navistarrv sells their MH business. In the mean time I have 7 months left on my warranty.
