Looking for Opinions on Keystone Montana for Full Timing

I'm in agreememt with Jack Spratt. We fulltimed for 4 years in our Montana 3455SA in Victoria, BC. It would drop to freezing on some nights but we did fine. A 250 litre propane tank helped and we had an auxilary heater for really cold nights. Also had a bed warmer. I loved climbing under those warm sheets on a cold night.
