More than likely it is the vacuum breaker, which I just replaced yesterday. Some trailers have a opening in the pantry, mine did not, I had to cut a hole in the back of the pantry to get access to the valve, mine was located 63 inches from the floor and 13 inches from the outside wall. I very carefully drilled a 1 inch hole in the back of the pantry, make sure the pocket door is shut, at that point I could see the plumbing and cut a hole to access the valve. Check out my thread on Vacuum Breaker, I posted a link to a Heartland site which has pictures of the valve and where it is located, they are very similar to the Montanas.
