FYI GD just build a new facility to do nothing but PDI on all trailers before leaving the factory. Hopefully that will take care of the delivery issues.
From GD web site:
"Following construction, every Grand Design product goes through an initial quality inspection process. This is usually the final step other manufacturers take before shipping their units. We at Grand Design RV believe that this “industry standard” process falls far short of producing what we would regard as a quality unit. So, at this point in the manufacturing process, we send each unit to our dedicated PDI* Center where it is meticulously taken through a rigid point-by-point inspection process and final finished. Only then do we consider it “Grand Design great”. In terms of time, building space and manpower, this step is a costly one. But we believe it to be an absolutely essential step in delivering the finest quality products to our dealers and customers."
