Ours is a 2014 3155RL, this is our 3rd season with it and we have made to trips to Florida these past 2 winters. It has been an awesome coach with no real issues, other than the front sliding doors for the closet will not stay secure when traveling. Our front A/C unit quit would not run on this last trip so I will have to get it into the shop between now and when we head south in late January. We love our Montana!
