Looking for Opinions on Keystone Montana for Full Timing

I think you would be fine with the Montana. I know we love ours but if I were you I would order it from the factory set up with dual pane windows, 614LT tires and the legacy package so you get the MCD day/night shades. And any other goodies you want from the start. I think Montana is really missing the boat by not offering disc brakes from the factory but we had them installed the first month we owned it and it's night and day compared to the drum brakes. Good luck.
