“This is for a 2021 Grand Design Reflection 28BH fifth wheel that we purchased a month ago. The slide out will not work properly causing major issues. We had to dismantle and remove the refrigerator and use a jack to prop up the slide out to get it to slide back in. This is after having to take apart the coverings to force the slide out back on it's track for it twisted and bent due to one side going out while the other side didn't. …”

“In 2021, we began noticing wall movement in the interior of the RV, fasteners, paneling and interior walls getting loose and moving. After more trips we noticed scratches in the flooring and wood chips laying on the interior floor when we would push the main slide out. We also began noticing the large slide didn’t seem to be closing tight to the outside wall on one end. After more inspection we noticed large roller marks appearing on the underside of the main slide. We scheduled our unit into the dealership for review. …”

“1)The glass on the Furrion fireplace exploded. There are photos, but it has been cleaned up. It was not under any stress. It was parked in our driveway, not in use, and the power was plugged in with ACs set to keep the internal temperature from any significant fluctuations. 2/3)While our direct safety was not at risk because it was not in use, you can see by the photo the blast and the shards of glass could have seriously injured anyone (person, children, or pets) who may have been inside. There are numerous reports of this happening to others, some of whom were inside. …”

“Excessive front nose cap/upper deck movement during travel (bouncing), suspect welds holding the riser wall and upper deck may be broken. Bottom flange of I-beam buckled over two foot span. Both diver and passenger side walls have pulled away from structural support. Floor dropped on both sides (bowing). Living room floor has slope to the back left since I purchased it new. Kingpin or pin box is not centered and shifted to where philon trim hung up on pin box. Passenger side wall appears to have shifted forward during transport. Bedroom doors no longer align with the jam/catch. …”

“I purchased a 2021 Grand Design Reflection 28BH fifth wheel in December 2024. Within the first year, I faced multiple warranty issues, including a $5,000 slide-out repair I had to cover out of pocket. Last summer, Grand Design’s CEO, Don Clark, stated in an email that the frame warranty had been extended to five years. However, my RV soon developed serious structural issues. The pin box and surrounding areas creaked and popped when hitching and unhitching. Stress cracks formed on the fiberglass front cap and above the main slide-out. The upper deck floor became spongy and creaky. …”
