I bought my Open Range in July (?) of 2015 and other than a broken Lippert axle spring I haven't had the first problem. We've only stayed in it for about 150 days or so and only towed it about 20,000 miles so I may not have tested everything yet. Everything I've looked at on it has been way overbuilt and of excellent quality. But it's only my 10th RV so I can't really compare it to every other make.
I don't know what moniker it was manufactured under but it doesn't say Jayco or Thor anywhere on it.
