I owned an OR and it was by far the most inferior camper I owned. It was nice, but the build quality was terrible. First year, the roof decking came up and had to have the dealer pull the roof back and fix that...consequently, they screwed the termination moulding down too tight and damaged the front cap of the unit...After many weeks trying to get it fixed right and them not willing to work with me, I unloaded the unit and bought a new fiver. Also the dealer said open range would give me $2500 towards a new camper, but the trade price with money added on and the trade I got at another dealer was exactly the same...Lerch RV in central PA is a shady dealership.
As stated above, they look great, but lack in the craftsmanship needed to be a great unit.
