2021 Grand Design Momentum 399TH Toy Hauler with three slide-outs!
The 2021 Momentum (by Grand Design) 399TH begins its flow at the rear garage: a generous 13-foot cargo zone with tie-down rails and fold-up sofas that convert into sleeping or lounge space. This unit features a washer/dryer.
Moving forward, the main living/kitchen area opens to an island countertop and central sink, flanked by a full-size residential refrigerator and a three-burner cooktop on one side, with theater-style seating and an entertainment center opposite.
A mid-coach bath & a half setup offers a full main bath (shower, toilet, vanity) plus a secondary toilet compartment for convenience.
At the front lies the master suite featuring a slide-out queen, overhead storage, dual wardrobes, and a TV wall.
Three power slides expand the space, and dual awnings (including a patio deck) extend the indoor-outdoor living feel.
The Momentum 399TH blends toy-hauler practicality with upscale residential touches, ready for both adventure and comfort.
While we will always attempt to provide you with a TRUE representation of every RV we market, during any purchase from Pop you will be encouraged to schedule an inspection from an independent, accredited inspector and every purchase WILL ALWAYS BE subject to your satisfaction with the results from your independent inspection and your own personal test drive.
We have several more Seismic, Solitude, Montana, and Cyclone RVs for sale. If youre in the Charleston, North Charleston, Mount Pleasant, or Summerville areas, please contact us to let us know what youre looking for and well get back with you today about any other fifth wheel trailer options we have locally that may meet your needs.
Selling your RV has never been easier. Pop RVs literally sells thousands of RVs every year all over the country. Sell through our nationwide marketing platform and make 20% more $ (compared to traditional dealership trade-in)!
