Momentum is Grand Design's toy hauler, and it is not one line but four. Grand Design — based in Middlebury, Indiana and a Winnebago Industries company since 2016 — publishes the flagship Momentum fifth wheel, the Momentum G-Class in both fifth-wheel and travel-trailer form, and the compact Momentum MAV travel trailer, as four separate rosters that share no floorplan codes. Together they span 28 MY2027 floorplans, from a $47,462 single-bedroom MAV to a $190,338 nine-berth flagship. This hub carries all 28.

The rosters are genuinely different machines. The flagship Momentum rides a 101-inch wide-body Super Chassis with drop-frame storage inside a five-side aluminum cage, on MORryde Independent Suspension 2.0 with disc brakes and six-point hydraulic leveling, with a 60-gallon dual fuel station, a 20-cubic-foot refrigerator and 140 gallons of fresh water. The G-Class fifth wheel keeps the wide body and Grand Design's new Omega Frame but moves to MORryde CRE3000 suspension, a Rotoflex pin box and electric auto-leveling, with a 30-gallon station — and lists roughly forty thousand dollars under the flagship. The G-Class travel trailer brings that garage to a bumper pull, with laminated aluminum walls, a full-sized rear ramp door and a flat, wheel-well-free garage floor. The MAV is the compact end: R-9 walls, a 24-inch DoveTail loading ramp and a garage pull-down screen.

Two things are worth knowing before you read the table. First, the MAV has no fuel station — Grand Design publishes N/A in the Fuel Capacity field on all five MAV plans and carries no fuel bullet anywhere in the MAV feature list. That is a published fact, not missing data, and it is the single clearest line between the MAV and the G-Class. Second, Grand Design publishes a garage length for every one of the 28 plans, which is unusual — Heartland publishes none for any Cyclone. Where the factory prints that length without a unit, we show it in feet and flag it, because feet is our reading and not the factory's.

Eight floorplans are profiled in full — two from each roster, chosen as the floor and ceiling of each, so the table spans the family end to end: the entry and the nine-berth flagship, the entry and the biggest-payload G-Class fifth wheel, the single-slide and the longest-garage G-Class trailer, and the lightest and the largest MAV.

The remaining 20 floorplans are catalogued here from the factory's published specifications, with full weights, garage lengths and fuel capacities. Their in-depth profiles are planned but not yet published.

Start with the tow vehicle, because Momentum spans a wider towing range than any other line here. The MAV is the only roster a well-rated half-ton should be considering: the 17MAV is 5,542 pounds dry with an 873-pound tongue, and its payload — 4,408 pounds, roughly eighty percent of its own empty weight — is larger than the entry flagship fifth wheel's, at a third of the price. The 28MAV stretches that to sleep six and adds the roster's only slide, but the payload drops to 2,700 pounds and the garage gets shorter. Neither has a fuel station.

The G-Class travel trailers are the bridge: a real toy-hauler garage, a 30-gallon fuel station and a flat wheel-well-free floor behind a bumper pull. The 21G is the entry — the only single-slide plan of the seven, 11,000 pounds of GVWR, a 1,056-pound dry tongue. The 30G carries the longest garage in the entire family at 20 feet 7 inches, longer than any Momentum fifth wheel including the flagship, plus a king bed — but read its 3,861-pound payload alongside that garage floor, because the space will take more than the axles will.

The G-Class fifth wheels are where the payload arrives. The 320G has the lightest pin of any Momentum fifth wheel at 2,300 pounds; the 394G carries 6,100 pounds of payload — more than any Momentum fifth wheel including the flagship 392M — and lists below the smaller 320G. At the top, the flagship Momentum buys independent suspension with disc brakes, the 60-gallon dual station and the 20-cubic-foot fridge: the 344M is the entry but carries the line's tightest payload at 3,090 pounds, and the 392M answers that with 5,386 pounds, a 17-foot garage and nine berths. If the 344M's payload math worries you, the honest options are the 392M or a G-Class.
