In the first year of owning my Montana High Country, I had 81 different issues. Some were a serious warranty problem.... like the brakes broke ... yea... really. The main entry door didn't close right, it drug and had a 1/4 inch gap in it ... really. Bedroom door broke at the door frame and completely separated from the wall.... really. The closet shelf and cloths bar completely collapsed ... really! Those are just a few things that went wrong.
After my 3rd trip to the dealership for warranty repairs, I took the bull by the horns and started fixing stuff myself. I realized REAL FAST that anything fixed under "warranty" will simply be replaced EXACTLY as it was when it came from the factory. They'll screw the same screws directly back into a Styrofoam wall that will collaps again at the first bump in the road. They will not affix additional adheasives, or extra supports, or do anything except restore (whatever the problem is) it to the way it came from the factory. This was completely unsatisfactory as the same problem occurred again on may of their fixes. Except for the front door replacement and all new brakes, springs, everything there, I went back AFTER their 3rd fix and re-fixed things myself. Lots of screws, Liquid Nails, extra supports, extra everything. After 1 year, I had a darn good trailer!
Now we purchased our Montana in the Fall of 2018 for a 2019 model. This was before Covid, so no one can point fingers on these horrid failures at Covid. It was just inferior construction and inferior design at the factor in the first place.
Now, today, OMG! I have a solid camper! Strong, sturdy, and stout. I've probably added over a thousand pounds of extra building material into it. But now, unless a tornado blows it away.... I'm keeping this one till I die!
If you want a good camper .... you simply have to fix the known problems yourself, be pro-active and do a little upgrading on the existing structure, and keep up on repairs before things happen. It's just that nature of the industry these days!
