2017 Keystone Montana 3791RD. This trailer is in nice shape and came out of a estate. This RV has lots of options including full size refridgerator,3 tvs, fireplace, and much more. This montana also has brand new tires with less than 50 miles on them. From my research this rv seems to be the cheapest 2017 3791rd forsale in the country. This unit would be over 100k to buy brand new today.
