Hi, I bought a 2011 Mesa Ridge by OR last summer. It was no really well cared for by the previous owner, and I've found a number of issues I've fixed. Cannot say they are the fault of Open Range by any means.
The trailer seems well thought out. Good usable floor plan. Appliances are decent, a step up from our last rig. I have noted a few small issues that I suspect are present with all manufacturers, screws that are screwed into nothing, when a fraction to the side would have put them into wood.
There is an owners forum online as well.
