The 2020 Keystone Montana 3120RL is a beautiful rig. It's built to sustain 4 seasons. It hosts both electric and propane heaters as well as a well functioning electric fireplace. It also has 2 AC units. So, you'll be comfortable regardless of time if year. This rig has been maintained well. It has a newer water heater, refrigerator (RV and residential) has new coils and rear workings (over $2500), new recliners, and all tank pulls have been replaced. Prices to sell. Couch slightly worn but sleeper functions perfectly. Rig also includes solar panels, automatic leveling system, and ample storage (both interior and exterior). Beautiful piece of equipment! Priced to sell!!
