Forest river Grey wolf RRBL- I bought this brand new and made serval upgrades to make it even more usable in winter and comfortable in the summer. You can go off the grid completely with its power Honda generator (see pics) that will run the air conditioning and quite enough to sleep at night. Also if you decide you want to camp in the winter I have installed tank heaters (see pics) on all three tanks to keep functioning even durning the coldest days. Also I have a complete set of air skirts (see pics) that go with this to blow up and keep frigid air from running underneath the unit and freezing pipes . This is equipped with a solar roof panel and to charge the battery (see pics). Also has a Bluetooth leveling system has you park your unit and try to get it level while moving the vehicle. This unit is a hunters camper dream! Bring the atv and stay for a week in a park camp ground with no hook ups with no problems!
