Example complaints

Body and structure: “Frame issues with the gooseneck area of the RV. We've got lots of movement with the RV in these areas where it connects with the towing vehicle. We have had lots of movement in the front nose area of the RV causing substantial movement evidenced by interior and exterior cracks and noises when pulling. We have taken the RV to a repair facility and the manufacturer has denied making repairs to make the RV safe.”

Other or unknown: “We noticed our pin box on our GD started moving when we hitch up. The wall inside the bedroom is showing wear from movement, the trim around the upper deck came apart multiple times, the flooring inside the bedroom had a hole in it from the bed gouging into it. When hitching up the wall is bulging out on driver side just off of the slide corner. Our slide stopped working and there are Gibs inside the wall of the slide that had sheared off rivets.”

Suspension: “I was informed that I have a broken frame upfront in the Kingpin area. I sent this to Grand Design and they denied any responsibility Grand Design Please find attached the pictures that were taken today (will Attach when sending final) and an email below to Blue Dog RV in Pasco show that I was very concerned about the front cabinets rubbing and asked to have them follow up with you. As you can see that email is dated Sept 7 2022 and is clearly still within the Warranty period for this frame problem. I have tried numerous times calling Blue Dog and left messages but no return calls. …”

Latches, locks and linkages: “The vehicle is experiencing severe frame flex causing the 2 passenger side entry doors to open while traveling down the highway in addition to rubbing the interior cabinetry against the side walls of the interior and causing the furnishings to be damaged. When the doors are wide open items can easily fly out of the vehicle while traveling making my personal items projectile hazards.
