Grand Design Momentum G-Class reviews

What a piece of ****! Must have had my stupid glasses on when we decided on a grand design. We have 3 pages of a legal pad full of things that don’t work or are less than perfect. I would love to list them all. The construction quality inside looks like it just have been put together on a Friday afternoon, both ACs is not run at the same time, the Cummins 4000 won’t run the AC and anything else...let alone both of them. 30 amp service for 2 15 amp items. Stupid. Slides are growling like they are about to snap, the fold up bed system slept ok for 2 nights, now we need a new mattress. The trailer shakes and rattles EVERYTHING out of its stowed spots, the water tanks fill up then spill out 100 gallons 2 times so far the “pressurized” water system basically creates a sipening that cannot be stopped. All the “wood” work is wallpapered cardboard, all the trim is plastic and flimsy, cabinets also don’t close correctly ALL.... oh man I could go on and on but I just get more pissed off! Don’t waste your money on this company. They are THE WORST EVER!!

Decided to go with the momentum 25g toyhauler. Thought we were buying quality, at least we paid for it. Been in shop for water leaks more than with us since may this year. Numerous small detail problems from backsplash glue coming loose, patio completely out of adjustment and patio awning same. Dining couch legs don't even touch the floor needed completely adjustment and drilled to work right. Missing rubber stops on ramp door causing paint scratches straight from factory. Pretty much a disappointment and waste of our retirement money.

2021 Grand Design Momentum 349M was more than what we expected. It is truly a second house on wheels. The best thing Grand Design could ever have done is add the residential refrigerator and gas stove. The kitchen and bedroom is very modern the shower is plenty big with the "car wash" showering system and bench seat, the back patio on the toy hauler is a bonus! Sleeps 7 comfortably with alot of privacy and the 2nd bath is key. Master bedroom felt like home with the king size bed and plenty of storage.

Really like the layout and the looks of this rv. Quality is bad and getting anything repaired is impossible. If I want to use my new camper I will have to do repairs myself which I really don't have the time for and shouldn't be forced to do. Just would like to enjoy something I spent 50k on.

We have only owned our toy hauler for 3 months and have been on 4 trips with it and we are not overly impressed with our purchase. We have already have issues with the roof leaking (caulk separating at seams) and when we called the dealer they said that is not under Grand Design warranty. You are to check the caulking monthly and fix any separation on your own. We brought up that we are starting to see rust spots forming on the frame and ladder and were told that is also not under warranty. The toy hauler is 3 months old and is cleaned extensively after every trip, there should not be rust spots forming at this point. Also, the captain chairs we were told are the best out there, but the screws and beads are already falling out of the bottom. The awning is a joke, any little rain or 5 mph wind your not able to use it. We did a lot of research before buying a toy hauler and thought we were purchasing one of quality, but that was not the case. Luckily we got the extended warranty which will help some, but to find a dealer that is not 2 plus months out, good luck. I would not recommend buying a Grand Design RV and are already talking about trading in or selling this one that is 3 months old.

This was a waste of my money. Since we bought this new the fridge didn't work, x3 windows leaking, and still leaking after 2 trips to the dealer, ramp leaking, a/c kicks off,trim falling off in two different rooms, railing system bracket falling off after two ''fixes'', patio door window fell out, a/c condensation runs onto the awning and dumps gallons of water on my grandson when it collapsed, awning leaking, stove vent leaking,sink faucet leaked from day one into all my wifes cabinets, water running out of underside of camper and the list goes on. When I talked to the dealer after my 3rd trip in, which costs me an average of $125.00 dollars in fuel round trip,I told them I wanted a replacement, they said call Grand Design, which told me to contact the dealer. TERRIBLE customer service on both ends. We traded off a good camper and have a total of over 100k invested in this, and all we get is the run around. If I ran my business this way I'd go bankrupt. Their service is crap on all levels and they make us feel like we are being unreasonable when all we want is to have something to enjoy rather than have to work on every time we go camping. POOR POOR POOR quality and follow thru on all levels, and we will NOT be buying another one of these toy haulers from them. They smiled , took my money, and pretty much said see ya later sucker. Beware, they ain't what they seem to be

Ok folks my wife and I purchased a Momentum 31G toy hauler about two weeks ago and took it out for a trial run this last week. We went dry camping in the white mountains of AZ. I had always believed from what I saw and read that Grand design put out a superior product. If this product is superior then Im glad I didn't go lesser. let me start by saying the freshwater tanks do not fill correctly, they have rerouted what drains into which tanks? meaning there definition of grey water is not what mine is and have become accustomed to. The furnace does not work correctly. And we need that here in NM winters. The outside patio landing railing are tweaked and need to be reworked. The backsplash is coming off the wall in the kitchen area. There are a few more minor things. My thing is with the reputation that Grand Design has and the money it takes to get one you like and will work for you, you would think things would work. I can tell you this "Things are not make like the used to be". is it just were we have gotten or is it the demand has so overwhelmed the supply? I bought this unit to enjoy and use it. not to spend my time in the shop for repairs. And even that the nearest shop to us is 2hrs away and they say its a 3mnth waiting list. One more thing this unit is almost a 36 ft tounge pull and let me tell you "be prepared to deal with sway issues" never experienced anything like this in my life. but for the money I spent I have to make it work. Not one person in Maint. or sales said a word about this condition. This is not very good PR work. The dealership said My ball/hitch height and the weight distribution hitch were good to go. "No Flippin Way" they were 3.5 inches off..."Scared the Hell out of us".

I bought this camper 8 months ago and niw it got a leak took it the the dealee i got from and they say they are not going to fix the leak 100% they going pay for 4 hours and its my responsibility to pay they rest i thank it bull shit its nit even a year one yet and i got a extended warranty with it for 7 year so what a warranty good for if it dont cover anything so will never buy a grand design again i will tell everyone how crapy There service they give

We purchased our 21G back in August. We've taken it on 5 local trips that total about 1000 miles. On the maiden voyage, screws and bolts were falling out of the Euro chairs. Two of the kitchen cabinet drawers were not in their tracks. The pocket door to the bathroom is warped resulting in rub marks. During the second trip, the microwave fell back out of its fitting. Third trip, we discovered water in the master bedroom and bathroom floor. Came to find out that the hoses behind the shower panel were not tight resulting in water leaking behind the panel and seeping thru beneath the shower basin. After fixing that issue ourselves, we checked the fittings under the bathroom and kitchen sinks and found they were also not tight. Thankfully my husband is mechanically inclined and was able to fix a lot of this ourselves. It is as if no quality checks were done before this thing got to us. You may be asking, why not just take it back to the dealer and have them fix all this under warranty. Here is the issue. We couldn't even get it in for service until a month after we called. When we took it in, it sat on the lot for 3 weeks. They fixed one item that was faulty when we initially bought it (fuel station pump handle leak). All the other issues we took it in for?? Nothing. They claimed they are waiting on authorization from Grand Design. It is now almost a month since we just went and took it back, issues still pending, and we still have no authorization. So the warranty is a bunch of BS. After our most recent trip, the clips that hold the glass panels in the back broke off. Luckily the glass panel itself didn’t break, but we now have that to add to the list. I will clarify that we aren’t doing any crazy off-roading with this thing. It seems even your standard local/highway travel is enough to bump everything loose. I will say that the floor plan and features are nice. It is small enough to easily tow, park, travel with, yet large enough to not feel like you are on top of one another. Overall, this has been a very frustrating experience. We didn't buy this item to not use it. What is the point of owning if you just have to take it back and have it sit there for weeks/months without any resolution? When I contact GD, I get a very canned response of what options I have, but in reality, the options are not good. You are at the mercy of service centers that are extremely backed up and waiting on GD to approve any work being done. We have opted to just have it done somewhere else (which is still 3 weeks out) and just pay out of pocket so we don’t have to be without our trailer. Hopefully we get reimbursed in our lifetime from GD, but I’m not holding my breath.

Grand Design quality exceeds other toy haulers. Grand Design's customer service is the best in the industry, period. You will see the quality of the unit when you step inside. We researched all major brands prior to our Grand Design purchase. We are happy with our Grand Design Momentum.
