Grand Design Momentum M-Class toy hauler 398M highlights:

Fireplace
Queen Bed
Kitchen Island
Dual Entry Doors
Universal Docking Station

This toy hauler is decked out in luxurious features you will want on your next outdoor adventure! With 18' of cargo space and a rear ramp door, you can bring along your favorite off-road toys too. You will start each morning feeling clean and fresh after a good night's rest on the queen bed in the front private bedroom and showering in the sunken tub with seat and skylight above. The kitchen has everything you will need to create home cooked meals, as well as a kitchen island with two bar stools and a USB charging port. Grab a snack from the kitchen pantry and relax on the four-seat sofa slide with a stowable table to set your food on. The garage area has an overhead bed, the space to add the optional two Happ-Jac's with rollover sofas and table below, and it is prepped to add the optional washer and dryer, plus you can even add the optional half bathroom! If you would prefer to have a residential refrigerator, you should check out model 398M-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!

Wonderful experience!
My wife and I would would like thank the entire staff at Wheels RV for going above and beyond normal business practices by helping us return our rental car as we were from a different state, and being from another state the entire staff made us feel very comfortable and un-pressured...The walk through

Andrew
Thanks to all the staff!
In February we visited at Wheels RV and found a Keystone Avalanche that was what we wanted. Shane was exceptional throughout our looking at this and many other models. The finance department made the transaction easy and the service department has taken care of every detail we have found in the time

James
Excellent experience
We bought our Transcend 265BH from Mike Harp and picked it up Friday. Our experience was fantastic. We flew through the paperwork and were introduced to Bessie for our walkthrough. She was fantastic going over every detail and explaining every detail often more than once as we are complete newbies.
