This is a very well built RV/Toy Hauler. We lived in ours for 8 months in the winter in an RV Park and were very comfortable. The fireplace allowed us to use the parks electricity to keep the place warm without using so much propane. Having the garage/2nd bedroom was a blessing as it gave an additional room for privacy as well as a large dining area. We were able to take long showers with the larger capacity water heater. The built in vacuum cleaner system made it convenient to keep the floors clean and not use up space for a separate vacuum. There is lots of storage space in the kitchen, bedroom and bathrooms.

We bought ours new and have had it 3 years. We upgraded ours with 8 T-105 batteries and a 3000 watt inverter. We boondock a lot out west, Colorado, Arizona and all places in between.

It is an awesome Rig and no complaints. Lots of storage and we haul a 4 seat side by side in the 14’ garage. I believe it’s hands down the best toy hauler on the market today!!!

BUYER BEWARE!!! I bought this RV back in 2017 it was a 2018 model Grand Design Momentum 5th wheel with ten foot toy hauler. We had nothing but trouble since buying it! The touch screen fails everytime we go out. Pushi ng the resent button does nothing!We cannot control the bedroom slide out, cannot control, lights,gages for gasoline, water tanks, grey and black tanks oh and the generator! You have to turn it on outside also the water pump! Batteries will not stay charged!! Then you cannot start the generator!! The app on our phones will not work now eaither!!! Do not buy with touch screen always insist on control switches! Also, the trailer is too high at 13.5ft it catches some of the large branches in the State Parks in Idaho also you cannot make the turns in the round abouts in the Federal Forest Parks!

We bought our Grand Design with plans to haul a small two seat car to tour the country. We are not full timers but have spent 4 months at a time in the unit and really do like all of the features and dependability. We had the dealer install tie downs that are heavy enough to secure the 2300# car and it travels very well with the car in the garage. We have had a few problems with the unit; generator had to be repaired and leveling hydraulic system had to be replaced, the support to get those repaired was great. This can be aggravating but what complex system doesn’t have problems from time to time, the support that we got was great. I just wish there was a bit more underbelly storage and my wife wishes the garage had another foot in length so she could have her washer drier (the car is 13’ long and the garage is 15’). For a towable, we highly recommend Grand Design.
