I have a 2021 Keystone Montana High Country 377FL for sale. It shows normal wear and tear as a 3 year old full time camper should. It has several upgrades which are as follows: On Demand water heater which can be used in the winter. It has in camper digital controls. The black/gray/galley tank valves have been upgraded to 12 volt push button. With the exception on the 2 windows in the loft area all windows has been upgraded to double pane insulated windows. It has a surge protector. It has a 4500 watt duel fuel generator. I have not used the generator with propane only gas. The generator will provide enough power during the winter to run all that you need. It will provide enough power during the summer as long as you only use 1 A/C unit. I have not used the outside cable/TV hookups. It has a washer dryer prep, solar prep, king size bed, sleeps 8, electric awning, self leveling, 2 exterior doors with one on each side, 18 cu ft refrigerator, ceiling fan. There are no leaks or soft spots. I bought a new camper is the reason I am selling this one.
