We really like the layout and the roominess.
On the first trip out we found that the rear grey water tank release handle could not be opened, and the oven is not level ,even when the trailer has been leveled. we had 12 warranty items after only 2 trips.
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.

Very large space. We have had. 6 adults slept very comfortably. The deck option is great for your morning coffee. Watching the football game outdoors is a plus. Easy tie downs for the toys. Only thing I would change is the rear awning. You have to figure it out it's not real easy.

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.

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.

We love it. We've owned others and we're convinced Grand Design Toy Haulers are the best combination of fun and luxury. The garage offers so many options beyond just otir cycle storage. We love the converted patio. So do the pets.

The kitchen has great storage with very nice finishes. Compares to your home. Pantry is wonderful and the side by side fridge is awesome. Not your typical RV fridge.

Pulls very nice. I have an F250 with an air ride system.

Pull into any camp site and be the envy of the camp.

Please do not get suckered into one of these. We took it out for 5 trips and had issues on every 5 trips. 2 of the 5 we had to have a service tech meet us at the RV park, and one of those they had to tow the camper back to the dealership themselves. None of the warranties are transferrable to a second owner, so buyer beware.
