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.

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.

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.

We purchased our 398-M in March of 2017..It is now December 2017 and in has been in for repairs after every trip that we have used it. At this time we have used it 6 times. It has spent over 6 months total in the repair shop. We have had problems with the refrigerator, heating system, air conditioning system, charging system, trim falling off inside, lights falling off outside, shower leaking, rear beds fell off the walls, blinds fell off, tires blowing, power switching from generator to battery power, and any more items.
We would not recommend this product to anyone.
We spent almost a $100,000 and the dealer knowing the problems with ours will only give us $50,000 for it. They know that it is a lemon and do not want it back in their hands. They said that they could not resale it due to all of the repairs made and it’s repair history.

Mike Thompson RV. has had the trailer for 3 weeks and still does not have the parts.
One of the cheep Chinese tires threw the entire tread , but did not go flat. No sign of road hazard but no one will pay me for the tire. Not happy with service. They give mostly excuses.
