2017 Grand Design Momentum Toy Haulers 5th Wheel reviews

The worst RV we have ever owned! Had a flat less then 10 miles from the dealer. First night the hot water heater didn't work screws were falling out everywhere.tank monitors have never worked Happy Jack bed frame pulled away from the wall the living room chair smelled like it was burning and stopped working! After only four months we had 27 different issues took it in for repairs and came out with seven new issues. took the unit to the manufacturing warranty department and they wrecked it. A disaster is all I can say! I will never buy another grand design!we bought the unit new in July of 2017 Show less

If I was GD, I wouls never use plastic sink/toilet fixtures again. I would find a different supplier for the theater seating. I would check all axles in stock and replace bad units prior to manufacture. I would assign one unit to each technician for final inspection and display their signature on a form for use by the customer for problems. This makes that employee responsible for that unit. You might be able to figure who is not doing their jobs properly by doing this. I wouldn’t want MY name on a poor unit. I would provide training to all dealers on proper PDI. We had many responses of “I don’t know” on ours. Make up a short video on the special differences for that model and send it to the dealers. Any dealership that will not provide warranty work because the unit was not purchased there should be fined or dropped. That is really bad form! Why doesn’t GD sell direct to the public? Why not have a new dealership owned by GD nearby? I think a lot of people would really like this idea. Have a handfull of “field inspectors” to go and help people get problems sorted out? You could have a few per sections of the country, pay them for time worked and expenses. Show less

We love the 399th except for the deception by dealer. Dealer told us unit included "my rv". This was not included. Told us the unit had 160 gal fresh water tanks. Wrong again we metered the water and the unit holds 109 gallons. GD customer service was ok but our dealer service was horrible. They acted like they were doing us a favor by fixing issues with coach. At this point we feel we may have made a mistake purchasing the momentum 399th. Show less

Overall we like our 399TH and we accept some of the simple fixes that usually come with a new camper. However, it seems like we have a list that wouldn't exist with proper QC: 1. The trailer arrived with the wrong interior. 2. The media chairs were mounted crooked and would get stuck on the window valance when reclined. 3. No hot water on city connection. We have to pull water from the tanks to heat it. 4. Half of the carpet in the loft wasn't even there. It just raw particle board exposed. I was told this was normal from my dealer! 5. Sliding door to the side porch is not square and the door doesn't close flush. 6. Garage glass door has a gap on one side, clearly not plumb. 7. Garage loft bed is not level. I have to push up on one side of the bed to place the locking pins in. I was told by my dealer there is nothing that can be done about it. I need to stand on a stool or use a pole to push the bed up while putting the pin in. 8. The porch enclosure tears a hole in the mesh when stowed for transport. The dealer said it's a design flaw. 9.Trailer was delivered with missing rubber keyhole covers. I was told they will not be covered under warranty even though it was delivered without them! 10. Batteries wont hold a full charge. 12.5V is the highest they will charge. The dealer is currently looking at that. 11. The door would unlatch even when locked under transport. The closed grab handle is the only thing keeping the door closed. I'm told the door isn't aligned with the latch catch properly. 12.Power converter was advertised as a 75W but a 65W was put in. 13. Kitchen slide does not close flush to the unit. 14. Fuel tank gage is backwards and reads the level in the opposite tank. There are also three options we paid for but wish we didn't and we feel a little deceived: 1. The king bed upgrade is not a true king, it's 6 inches narrower than a actual king. We upgraded so I could use our Tempurpedic mattress for my back only to find out later that I paid for the king size option and it won't fit my actual sized king. I now have to buy a queen Tempurpedic to replace the stock mattress but the queen mattress is too small to fill the fake king size platform. Basically I paid for an option I can't use and on top of that I need to spend even more money because of it. Stick with the queen unless you plan on keeping the horrible stock mattress! 2. The so called removable carpet kit for the garage area is a joke! It is literally a roll of felt that isn't even cut to fit the garage(see pic)! We had the understanding it was carpet that matched the carpet in the rest of the trailer. We at least got a small piece of carpet for the door step.The option should be title "unmeasured/uncut removable felt" because it is definitely not carpet! Buy a remnant instead from Lowes or Home Depot, it will be actual carpet and it will be cheaper too! 3. The optional stairs for the ramps have been useless for us. We have yet to find an area that once you get leveled the stairs will reach the ground, even with the legs fully extended(see pic). I have to use wood blocks to place under the legs even on a hard level surface. The only time they work properly is on a flat level surface without the leveling jacks extended(like at an RV show)! The side porch stair mounts were not measured properly and the stairs will not mount evenly because of them. I'm waiting for my dealer to see what they can do with that. I would love to have my money back for these useless options. The camper is nice overall but there seems to be some deceiving with some options, intentional or not....research the options closely or you may not be getting what you think. This is our first camper and our lessons learned were expensive. Show less
