Grand Design Momentum M-Class 5th Wheel reviews

We've been living the dream with our Grand Design Momentum 388M Toy Hauler 5th Wheel for years! The 14' garage is not just for toys; it's our fancy office space! The living room and kitchen layout is a total win, and the TV's diagonal placement and groovy blue LED lights in the entertainment center set the perfect mood when we enter. Plus, the abundant storage thanks to the 8' 8" ceilings and tall cabinets makes organizing a breeze. Oh, and we can't forget to mention the awesome layout of the bedroom with his + her closets. Life's a blast in this bad boy! 🚀🌟 Show less

Trailer is falling apart after 1500 miles and the warranty is no good. The doors won’t stay closed going down road. Already ruined the back door. The front door strike is put in wrong spot for latch. Tried to move it but factory has so many holes in door jam strike plate won’t stay on. None of the compartment doors close correctly. The propane tanks are held in with banding iron and clips. The banding iron is very sharp and I have cut my arm open that requires stitches. Very pore Desighn . The awnings are installed so hi on camper they don’t do nothing. I spent 100,000 and Bishes RV sais I have to pull it back there to get fixed. Bishes Rv took my money but won’t stand behind there promises to come fix it. When you buy a camper you only get 60 % what your promised. Show less

This 5th wheel has been amazing for our family. With the size it made it comfortable to get out of the weather as needed on our trips. Enjoy coffee on the couch with the fireplace going. All with the ability of 4 tv's for everyone to have options.. kids, friends! I Show less

I love this RV and there is nothing I would change about it. I have owned other brands, and Grand Design is by far the best. Grand Design Customer service is always top-notch and you couldn't ask for more than that. They really respect and value the customer after the purchase experience. Show less

Purchased our rig after great feedback from friends who own a Momentum. First 5th wheel ever! Writing review so people can see positives. Most people only post negative reviews. I wanted to make sure I spread the positive feedback. We don't regret it at all. Family of 6, a teen, 2 young boys and a baby. So you know we are putting it to good use. Typically we are at the sand dunes. Lots of dry camping. We pull onto the sand just fine. We let air out in our tires both truck and trailer. It can definitely be a bumpy ride when pulling in the sand so I expect things to move around or loosen up. We have only had the curtain cover frame around the slides come loose. Fixed easily. Traded in a Silverado for a 2020 GMC 3500 Sierra, Diesel. Pulls effortlessly. Overall the only thing we had to fix besides the curtain frames was on the shower. We just added extra sealant to the glass rail to avoid leaks. Also the kitchen curtain won't pull up anymore. We will fix later. Bed licks so we upgraded the mattress with a tempurpedic mattress topper. Life savor. Our 349m is a 2020. I absolutely love it. An awesome buy for an active family. We can fit 3 adult quads and 2 90's in the garage. A 12.5 ft side by side easy. The hydraulic system makes the rig! Generator is loud but what isn't. 3 AC units for hot summers pretty cool. Heater heats up entire trailer except garage... Tanks are usually off but you get used to it. When camping with full hook ups, it's a great time. No problems with internal systems or hook ups. This was a decision between a Raptor 415 and the 349m. Very happy with our our purchase. Show less

Alpin Haus have been terrible in customer service. I had leak repaired 3 or 4 times and they charged me for it. Livingroom slide out leaks occasionally. Lights on the front work for a short period of time and quit. The refrigerator quit on me in the middle of a 13,000 mile road trip, I could not get alpin Haus to call me for repairs or any call at all. I still have issues with the camper.I had problems with hotwater heater not working. That's about all I can think of right now. I think this is more than anyone should have with a rig this expensive :( Show less

Like any new RV we had a few issues. The the first issue was with the second water tank not filling completely. We weren’t comfortable going to [Dealer] to get the work done, Grand Design was completely ok with us going wherever we were comfortable to get the work done and covered parts and labor promptly no questions asked. The second issue was with a faulty suspension spring, this was after our warranty was expired, they paid for parts and labor replaced both springs, upgraded both sides quickly no questions asked. Their rep called and emailed to make sure we were happy. We love our 349M and continue to make memories that will last a lifetime. I will never purchase another brand. Show less

We purchased a momentum 349m . We ordered it so we could have the way we wanted it full body paint and all . Well this has been the biggest disappointment of any rv we have ever owned . They base there whole advertising format on quality and 250 point inspection. I would terminate the people doing the inspection if this is true . So the camper was built and delivered , we’re going through inspection and the paint finish is terrible looked nice from a distance. You get up close fish eyes , spots and runs in the finish every where. So the take it back to Indiana and repaint it , it takes six weeks !!! They supposedly do another inspection. We go pick the camper up looks good . Now we’re ready for camping . Turn on ac the one doesn’t work at all . Take it back to dealer there was a ground wire not connected ( thought we had this 250 point inspection process ) oh and by the way the dealer is seventy miles from our house . Now our first camping trip , extend the awning and led light doesn’t work in main awning ( thought we had this 250 point inspection process ) . There wasn’t cable access in camp ground so we rented a dvd awesome picture on tv we have the Rockford sound system upgrade and it sounds good one hour into the movie picture freezes ( unbelievable) eject it and now it will not load let it cool down or whatever it needs to do several hours then it will play . It did this for four nights and four different dvds , the the hot water handle on bath faucet started making terrible squeaking noise ( plastic junk ) none of our other campers did this . Had to take it back to dealer to get repaired on the way back left rear tail light on camper quit working probably a poor wiring connection. So we have owned the rv for four months and it had been at the dealer or manufacturer for seven weeks and counting , this is very disappointing and misleading when the format is based on quality and inspection process , that was why we bought the rv on that advertisement and paid for it in full .we have had more problems with this camper then all of our other campers combined this is our sixth one . My personal experience should have stayed with a keystone product oh well . Show less

Love out 349m. Thankfully I have an engineer minded husband who understands how things are supposed to work, which is good as the walk through with dealer was grossly inadequate. I think the dealerships (any dealership,any brand) should have to prove they “know” the product before they can carry them. Show less
