2021 Grand Design - Momentum Floorplan: 381M (Toy Hauler)


Used once last year. Moving soon and we don’t want to take it. Ready to use now.

Grand Design Momentum M-Class toy hauler 381M highlights:


Queen Bed

Kitchen Island

Dual Entry Doors

Bath and a Half

Universal Docking Station

Load up your favorite off-road toys into this luxurious toy hauler! The garage area features an overhead bed, an area prepped to add the optional washer and dryer, and the option to add a Happi-Jac with rollover sofas and table below it, plus there is an entrance into the half bathroom. The kitchen island has two bar stools, a fold-up countertop, and a USB charging port for your convenience. The four-seat sofa slide is a great place to relax on at night, or you can switch it out for the optional sofa recliners and free standing dinette instead. The full bathroom has a shower with a seat and a skylight above for natural lighting as you get ready each morning! If you would prefer to have a residential refrigerator, you should check out model 381M-R!

Live big and play even harder with any one of these Momentum M-Class toy hauler fifth wheels by Grand Design! The CRE3000 MORryde® suspension system improves its towability with a smoother tow and better protects from damaging road shock. Unlike many other toy haulers, Momentum features an exclusive garage floor design with a R-40 triple insulation in the garage floors, and a Weather-Tek insulation throughout the roof, main floor, and side walls. Pump up the volume and shake things up with the optional Rockford Fosgate speaker package that comes with a 12" subwoofer, a 400 watt amp, and eight 6" full range speakers. You will also enjoy the fully enclosed fuel pump station, the door side exterior spray port, and the four mandatory packages full of extra features that will make your next camping adventure luxurious!
