RV Description

This is a 2021 Grand Design Momentum 399TH - working to get the title of the ad corrected.


Our 2021 Grand Design Momentum 399TH is a luxurious fifth wheel that has barely any miles/use on it. We had it parked (in a very shaded area) at a local RV campground and used it about 15 weekends each summer for 2 summers. With only 800 miles (or less) on it, this practically brand new RV is ready to hit the road and provide you with unforgettable adventures.


The interior is like new with many upgrades such as a 3rd air conditioner (The 3rd AC has a heat pump), upgraded tires (Load Range H Cooper Tires) , Rockford Fosgate sound system, and a king-sized Purple Mattress in the master. Everything is very clean as it's been used very little.


One of the standout features of the Grand Design Momentum 399TH is the 399TH trim level, which offers a range of upgrades and amenities to enhance your camping experience. From the well-equipped kitchen to the stylish bathroom, every aspect of this RV has been designed with your comfort in mind. We have added a shower curtain to the main bathroom, baskets for the pantry, a mini-fridge for the back bedroom (toy hauler area), and are willing to also include the 2 twin beds with mattresses we added to the toy-hauler space (there are still the drop down queen bunks there too - but we utilized the top one only plus added 2 single beds on the floor).


Ours comes with a generator with MAYBE 25 hours on it - we ran it only an hour a month or so as recommended). We rarely used the bunk sleeper area in the kitchen space as our son was too big for it so that mattress pad up there is like new. We also added a water softner, JT strong arms, and several other extras we will include.


We love this camper - and are sad to sell, but our 3 kiddos turned into teenagers with jobs and sports schedules and we no longer have the time to use it each weekend.
