Heritage One Ground Control?

I'd never even heard of them until your post. I'd be leary to be honest. They started production and were shut down around the first of July 2010. They only had 2 lines, Ground Control and Due West. Though most all RV us the same parts, a company that doesn't last long usually isn't a sign of quality building and construction. Unless you're very mechanical and can do your own detailed inspection I'd keep looking.
