I bought this thinking it was a good toy hauler.Four years later I am putting over $3000 in upgrades to worn out and broken springs, three blown tires. Now I find out I can’t even put heavier tires on these rims. Warranty and corporate office response was it meets specs, but yet they no longer put lippert axles on them. They claim gross weight on this is 16500. The spring shop that’s been in business for years said it had 3400lb springs. The camper is maxed out at all the time with my Harley in the back and a half tank of water. And you should know if you are putting a golf cart in there you can add another 300 lb in weight. There answer was always it meets specs. Very dissatisfied with the suspension, if your looking for a toy hauler think twice about this one or any other that doesn’t at least have G rated tires. I also do all my mechanic work so that has saved me a tun of money remember Rv shops have around a $180 an hour shop rate.

We have been full-time for many years, the last 4+ have been with the Grand Design Momentum 328m Toyhauler. Our criteria when shopping is that kitchen, bath and bedroom can be accessed without having to extend slides but we want to take the Goldwing and now we have a side by side perfect for the garage.
This Toyhauler and the manufacturer Grand Design has been excellent. Sure, there were a few bugs to work out (all of them have them) but being mechanically inclined and technical to talk with the Manufacturer to get through it, we've been extremely happy and Grand Design is the best at empowering the customer when things do come up. It's been a pleasure to enjoy our Grand Design for over 4 years since we bought it new. Roll on and Happy adventures.

We spent a combined total of over 24 hours on hold trying to get warranty work done on our Momentum, not receiving callbacks after numerous messages, multiple emails, parts sent to incorrect addresses... we finally received 2 reimbursement checks from Grand Design: only to cash them and have them bounce and being charged an additional amount for the privilege of receiving bad checks from Grand Design. Now we have to start the ENTIRE arduous process over again.... I strongly advise anyone considering buying a Grand Design product to consider their completely useless warranty process when making their decision. If I could give a negative 100 star rating for factory/warranty support, I would.

Love this floor plan. We use it as long term living when our house is on Air BnB. Lots of issues getting a full house inverter installed by the dealer. Unit arrived with brakes burned out. Lots of issues with Lippert components. Awning mounting bolts missed structure. Mattress was junk. Too bad the components are not as good as the structure.
My Heartland Riad Warrior never had so many growing pains. Still love the M3 though after working through these growing pains.

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.
