I purchased a 2020 Montana High Country from Mike Thompson RV. This is the second RV i have purchased from Mike Thompson. I broke a side window while backing in my driveway. I made an appointment with there service department to have it repaired. They had it for 3 weeks and called me saying that the factory sent the wrong window. James Basham service adviser told me if I didn't want the frameless window installed that i would have to wait 6 to 8 weeks for the correct window with a outside frame like the rest of the windows. I didn't want to wait so I had them install the frameless window so I could at least use my RV. With That being said I order the direct replacement window from Lippert Corporation. James Basham service adviser said that was the window the factory sent. I got InTouch with the factory and found out that Mike Thompson ordered the wrong window. I would not buy another RV from Mike Thompson or have any work done at there service department.
