2019: “We were in route to assateague for the weekend when our awning somehow opened & detached from our camper while driving at highway speed on rt 50 in maryland. I believe it failed due to being blown open by the wind, but I am unsure. When it detached, it violently flailed around damaging the exterior of the trailer. We were on the chesapeake bay bridge when the event occurred with the awning flailing around by cars & the bridge structure. …”

2016: “My 2016 Grand Design Momentum 327m uses lippert axles. Three of the four grease seals leaked and were found during a state inspection. The grease contaminated the brakes.

I contacted Grand Design regarding the issue. I was told that new models were built using dexter axles to solve the problem. …”

2017: “I purchased a new Grand Design Momentum 350m at holiday world katy, texas. After taking delivery of the camping trailer & checking hook-up to truck, lights & brakes in the parking lot, I towed the 350m about 50 miles across houston. I was quite concerned with the poor braking quality of the camping trailer, even after increasing the truck brake controller gain to 9.5 (of possible 10). I thought maybe the brakes needed more 'break-in time' so a couple of days later I slowly towed the camping trailer 400 miles to my home in s. Texas. …”
