I would buy another Springdale if in the market. Had no issues with my 2007 29RKL.
In fact, Keystone in Oregon sent me blueprints of the ceiling structure so I could install a roof vent in the kitchen and a blueprint of the structure in the slide out end wall when I wanted to install a handicap access door. Excellent Customer Service and response.
BTW, Keystone pays the dealer a fixed amount to do the PDI or Pre-Delivery Inspection. A proper PDI by the dealer would have discovered that defective P-Trap. That one I blame on the dealer.
