My wife and I had the same type questions, and we scheduled a factory tour, prior to our purchase. That was in , I think, March of last year. After that, we felt that the entire Grand Design team was far superior to any other, so we ordered our unit. We have been very happy with our unit, with a few minor glitches, that I took care of myself.
In closing, it would be my recommendation that you do the same, even if it involves some expense. Considering how much the units cost, it is a good investment, in my opinion.
