I have some friends that have 29-ish foot Imagine by Grand Design. They've live in it full time for 3 years now and have had little in the way of issues. What I noticed about the Grand Design is the general "lower feel" when it comes to some standard features. 5 gallon propane tanks and not 7 gallon. No spare tire cover. No propane tank cover. Tons of Lippert. Plastic sink.....though mine had a plastic sink too. Also to my knowledge, the wall thickness is 1-1/2" I think and not 2" like Outdoor RV. I didn't notice any workmanship issues with their trailer. At least nothing that really stood out.
