STRUCTURE

The frame of my trailer sustained damage due to flexing from poor design. I was lucky and noticed some loud noises when transitioning weight to the king pin on the truck. A lot of creaking and groaning. Because of all of these noises and what I had read online, I had the trailer inspected. The inspection found the frame moving within the structure when the weight transitions from the stabilizers to the king pin. Additional damage was a crack in the structure that holds the wall to the frame and many bent gussets that are designed to give the structure strength. This design is substandard. I understand the whole thing is designed to work as a whole to provide strength, but there are weak areas in this design. First is the use of lag bolts into a soft wood as a method of connecting the frame to the wall structure. This needs to be into metal or aluminum allowing the use of bolts and a thread locking compound to prevent loosening. Lag bolts into wood on a structure designed to withstand dynamic movement of towing is inadequate. This will always loosen over time transferring the load to other areas of the structure and the damage many are seeing. My trailer has been repaired, but I'm not sure if the new gussets and additional lag bolts will be enough because they are still using wood as a structural component. My trailer is a 2020 and the 5 year warranty will expire in September. I'm not sure where I will be after that when the next repair comes. I don't have a lot of pictures because I was out of town when they did the inspection. You can see the break in the wall support showing that the wall was moving after is separated from the frame. The pictures show how this bent the gussets that are designed to give the structure support. Like I said, I saw this problem online and asked for in inspection before I had real problems. If I had waited, the damage would've been much worse.

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.

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. The vehicle has been diagnosed for frame issues by an authorized repair facility "Busted Knuckle RV" in Las Vegas Nevada. Grand Designs did not authorize the repair facility to perform the necessary inspection work and Informed the shop that I would be liable for the cost of the initial tear down inspection that can average $5,000.00 The unit has had saw dust and rub marks on the interior since we first purchased the unit and transported it from Texas to our home in Arizona. We were not sure what caused this rubbing of the furniture on the interior and were later informed that this is caused by extreme frame flex or failure. The pinch style moldings that cover the seams on the front cap of the rv have loosened while driving and flap in the wind while traveling down the highway, I have since been forced to apply silicone to keep these in place. This style of molding is designed to stay in place without having to apply any adhesive to them. The doors have opened while on the highway on several occasions causing great concern considering we only use the vehicle approximately 6 trips per year.
