For the OP...
Overall quality is terrible.
Grand Design quality is no better. I was considering a GD purchase a while back and joined the Grand Design Owners FB group- they suffer the same issues as everyone else. They do seem a little more customer focused on getting it fixed, but these are often things that should have been right from the factory.

You clearly didn't make it far enough west then. I was broken down twice in one day (really 1 event, but I'm stupid sometimes).
