We bought a brand new 2022 Grand Design Momentum 395 MS in June 2022. We shortly started having issues with everything. The door couldn't be shut unless you slam it. The garage door and track broke. We weren't able to use the patio or entrance at all. The sewer line cracked and started leaking. (Not during winter months). The wall separating the garage from living room separated from the ceiling. The walls were coming apart in the bedroom. The furnace would not turn on in the middle of the night unless I got up and turned it on manually every one-two hours. We had the ignitor board fixed. This only worked for a couple of weeks and then we started having the same issue again. We took it into Bish's where it sat for 5 months while they tried to fix everything. They ended up replacing the entire furnace and everything else. The ceiling immediately separated again. The oven ignitor went out and the entire oven had to be replaced. After another couple of weeks the furnace started doing the same thing. We had the motherboard replaced and the command center. The ignitor board went out again and had to be replaced. We had to replace the female power outlet to connect to power. We soon discovered that the water system is completely defective and started leaking after 20+ hours of repairs we finally stopped the leaking. Due to the tubing and clamp job they did during manufacturing the entire water system needs to be relined and redone. The lines in the shower need to be redone requiring the walls to be removed. The lines underneath the sink all need to be fixed as well. We fixed the propane regulator finally fixing the furnace issue during the night. After 3 months of infrequent use of the BRAND NEW furnace the motor burned out again. The entire venting system is not correctly done. Per the Suburban manual we are supposed to have 4.4 vents we barely have 3 and that was after fixing the 4 inch vent we had the one in the kitchen opened out more because it was never completely opened during manufacturing and occluded approximately 85%. The foam seal was blocking the air flow we were only receiving 1 x 1.5 in of air flow through a 4 inch duct. In order to prevent the motor from continuing to burn out we need to add another 4 inch and 1.5 in vent. We use this 5th wheel for work. We are unable to leave it anywhere for very long without winterizing it because since the furnace won’t work everything will freeze. This is a defective unit. Since the duct system is a preexisting issue NWAN will not cover these expenses. The faulty duct system is causing the motor in the furnace to burn out and it only takes a couple of uses of the furnace to burn it out. The issues with this camper has disrupted our work, displaced my family, and has cost us thousands of dollars in repairs on top of traveling, hotels, loss of food. We are not new to 5th wheels, this being our third. We wanted the Grand Design because it is marketed as a high-quality top of the line product. We are grossly dissatisfied with Grand Design and their customer service team. We have called and are told they are unable to disclose any information about our claim only the agent can. I have sent two emails since 1/4/2024 and have not received any responses. We have already spoken to the dealership. We don't think us eating $35,000 + is fair for a defective product Grand Design manufactured. We are defeated and done. Our family is separated and displaced. The issues are never ending, we feel like we finally get everything fixed and the next day it’s something else. We don’t want this camper anymore or any other camper that Grand Design has touched.

We purchased this RV because we wanted opposing couches, along with a dinning table and large kitchen. This is the only toy hauler on the market we were able to find that fit all these criteria. We lived in this full-time for over 6 months and absolutely loved it. At first we weren't sure if the exterior storage space would be large enough, but we were able to bring along everything we needed (and more). The large water tanks combined with over 60 gallon capacity for fuel allowed us to boondock without hookups for multiple weeks without needing to fill up or dump. We used the garage area as a kids room/play room and it worked out excellent. The One Control center was great as well that we could control the RV from our phones. This allowed us to adjust the air at night, turn on exterior and interior lights, water pump, etc... from anywhere around the RV. If we could go back, we would get this exact RV again. No question!

we've had this RV since Aug 2019, with little to no problems..the shower glass door wasn't properly sealed, however that was an easy fix, a few of the wood moldings came off, again an easy fix.. June 2020 our Norcold Fridge which by the way sells for approximately $5000.+ broke...GD would not pay to have someone come out to fix it because we were in a small beach town at the time...so we had to take everything out of the fridge and freezer and put it on ice, needless to say we still lost hundreds of dollars in food...we ended up taking it to a service shop which they did the least expensive way to fix it, by resetting the temperature switch, which worked up until July 9th..had another service person come and replace a fuse which again worked for about an hour..now its completely dead...GD refuses to reimburse food loss, service call and Christine Holland at the GD company basically told us too bad its our problem... we bought this brand because we heard that they work with full time RV'ers and that they provide service throughout the US and Canada without having to bring the trailer to someone..THEY LIED!!! they don't care if you are full timing, they said its not their problem, that they do not care about our loss or inconvenience !!!!

I would recommend running away, to another brand. We have owned our 395m for about 7 months. Something breaks about once a week, leaks, doors hung wrong and so on, with a major issue every other month, refrigerator took 2 months in service, now the water heater and that was after they 'fixed'the first round of problems. I will never buy another grand design and would absolutely not recommend anyone else to get one. We have had some luck getting grand design to approve repairs but it takes forever and God forbid it is a sub part, then you have to go thru that supplier service. It doesn't help that something else breaks right away. Never again. Horrible quality. Have to add air bags to help the bucking during towing. If I had the money I would go buy something else and drop this thing off at the nearest junkyard.
