montana 3790 warranty denial

That's a horrible story to hear. I bought our Montana Mountaineer 5th wheel from them in 2007 brand new and they even set up my truck with the 5th wheel hitch and 7-way cable. This almost sounds goofy in that we were welcomed with open arms when time came to pick up our 5th wheel. Pictures were taken and posted and it really felt like a caring customer appreciated company. Everything worked when we left, and we never had to go back for service excluding the fading,curling and peeling decals that at the time was wide spread. They also waxed my local Keystone dealer by many thousands. I'm really surprised by your story and hope it's resolved to your satisfaction.
