Montana's and OR are both good units. We have the 162nd Open Range made. It is a 2009 purchased new in May of 2008. Had some small glitches at first but overall we really love the unit. I will say that the factory folks are excellent. FYI Jayco bought Open Range. The company is called Highland Ridge dba Open Range. It is still a stand alone company. Over the weekend at Good Sam Rally we looked at a new Open Range 388RKS with triple insulation. What a rig. It has the rear kitchen and almost 40' long. Also Open range has a 2 year bumper to bumper warranty. Would I buy another one..Absolutely. Good Luck in your search.Open Range is now in the 19000 unit.
