Like Penman, we too have a Bumper pull JT337 travel trailer, although a bit older than his. Ours is a 2011 purchased in Jan. 2011. Only major issue was some severe inside tire wear on one tire. That was right before the two year warranty was up and OR replaced the axle at our dealer without any issue. The other few typical minor issues were also taken care of at our dealer under warranty. The 2014 Open Range Texas Rally Penman referred to was a blast. We just happened to be parked on the next row across from them. Definitely enjoy the Open Range Owners forum, loads of info.....cC
