From the pages of I RVing: Spring 2023

Haul That Momentum

AN ERA OF EPIC TOYS is upon us. The signs are everywhere—never clearer than in the presence of Grand Design’s M-Class 336M. Like a Micro Machines commercial from the 90s, there always seems to be something more to the playset. When that rear latch opens, out comes a bike! Then a kayak! Mix and match for any adventure. But the Newmar Super Star? Well, that’s the one toy everyone is saving up for. Turn a few pages, and we’ll unwrap why.

An Extreme Toy Hauler with No Compromise

The Momentum M-Class didn’t get this good by accident. It was all by Grand Design.

WEIGHT ISN’T EVERYTHING when it comes to momentum, and the Grand Design Momentum 336M fifth wheel toy hauler is all the proof you need. Lighter than its full-sized counterparts,
the M-Class lacks nothing. Equipped to transport your toys off-grid, it’s equally equipped with an innovative interior that creates space and wows you with its decadence. Were you expecting compromise? Ha! Maybe for other toy haulers— but not the M-Class. Toy haulers—even the fifth-wheel, not-so-light-on-luxury versions like the 336M—belong in the wild. (We feel certain Bill Burke and Nate Kennedy would agree with us here, but you can check Page 58.) And= Grand Design’s M-Class wouldn’t have it any other way. The H-rated tires are heavy duty. The 7,000-pound axles with ABS brakes are heavy-duty. And the MORryde® CRE3000 suspension system and anti-lock brake system are geared to tow your toys to their proper launch point.

Once you’re there, you can extend the awning and enjoy the rites of Spring, cooking in the outdoor kitchen while watching your outside LED TV. And when you’re ready to break out of base, you can drop the rear ramp to access the garage. Because when the toys come out, that’s when the fun really begins. Just above the garage, there’s a queen lift bed that ascends and descends easily to make space as needed. But once lowered, no one would guess a garage lies beneath it. Windows bring light in across the headboard above the mattress, and the bedroom’s wardrobe space is surprisingly spacious with his-and-her capacity. The bedroom connects directly with a three-piece bathroom, complete with a glass door shower, teak bench seat, and skylight. And when you rinse the dirt off in luxury, you’ll get what the 336M is all about.

The Summit of Entertainment

Ascending a few steps, and nestled just behind the front cap, you’ll enter one of the most exceptional living areas we’ve seen. With two 70-inch trifold sofas, you can make it into an extra bedroom space, but you’ll be tempted to keep it just for yourself. It’s spacious and separate with a TV, fireplace, and theater seating (in addition to the sofas). The M-Class 336M is fitted with a Rockford Fosgate stereo entertainment system that you can control with an app. This means there’s gonna be a party—regardless of how many guests you have.

The Galley in the Valley

With an elevated living area in the front and an elevated bedroom in the back, the kitchen is truly the valley of the cabin. And what a valley it is. The hardwood cabinets have glass curio doors and hidden hinges. The butler pantry doors vanish, folding back into the pantry itself. The island has a residential kitchen faucet and contributes to what is already an overwhelming amount of counter space. Across from it, a free-standing dinette lives comfortably in the slide—a comfort that’s shared by everyone at the table.
