We bought our 2007 Montana Mountaineer used. In 4 years of full timing, we have had one problem that was not self induced. The window in the bedroom broke and I have never found out why. I did not like the cheap spring shackles or original brakes, so I replaced both of those items. The dry nylon bushing spring shackles were replaced with Mor-Ryde wet bolts and the 6000 pound brakes with 7000 pound self adjusting. The interior has held up well. Of course, I am biased, but I do not think you can get a better fifth wheel for the money than Montana. There are better units out there, but the price difference is large.
