Check out the Grand Design owners forum on Facebook. Yes GD uses Lippert and there is better quality components out there but they are more expensive. If GD installed them people would complain they cost to much you can't make everyone happy. From what I've read Lippert stands behind the problems for the most part. GD customer service is outstanding! You have to remember these things are rolling earth quakes going down the road. We toured the factory and I was impressed with what I saw.
