Thor Motor Coach Challanger Class A - Gas reviews

I think to factory need someone to check every item on an rv before it leaves the factory. The passenger window stuck hard to slide. I have used every it the dealer say to try. A hammer will be next so Thor can replace the window. It only a few items don't work so between factory and dealers the item stop working. Then we are stuck without our MH for weeks waiting for approval and parts. Items not in parts back to vender and and waiting time. Show less
