01 What makes it unique
The Momentum MAV 24MAV is a travel-trailer toy hauler 29 ft 11 in long with an 18 ft garage, on two axles with no slide-out and no fuel station listed. It is on Grand Design’s Momentum MAV roster for 2027.
Grand Design’s page lists an unloaded vehicle weight of 6,650 lb, a GVWR of 11,000 lb and a tongue weight of 1,200 lb. It publishes no cargo carrying capacity, so none is printed or computed here. Tanks are 90 gal fresh, 74 gal grey and 37 gal black, and it sleeps 3.
Grand Design’s page names the 27MAV and 28MAV as comparison floorplans.
How the 24MAV differs from the other eleven Momentum travel trailers. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.
- Tongue weight as a share of dry weight, 18%: largest of twelve; next is the 27G (17.3%).
- Sleeping capacity, 3: second-smallest of twelve, between the 17MAV (2) and the 22MAV (5).
- Dry weight, 6,650 lb: third-lightest of twelve, between the 22MAV (5,900 lb) and the 27MAV (6,900 lb).
- Length, 29 ft 11 in: fourth-shortest of twelve, between the 21G (26 ft 11 in) and the 25G (30 ft 11 in).
- Interior height, 7 ft: lowest of nine, level with the 17MAV, 22MAV and 27MAV; next are the 21G, 25G and two others (7 ft 7 in).
- GVWR, 11,000 lb: shared with the 21G, 27MAV and 28MAV; of twelve, two lower and six higher, nearest the 17MAV and 22MAV (9,950 lb) and the 30MAV (12,000 lb).
- Tongue weight, 1,200 lb: shared with the 28MAV; of twelve, four lighter and six heavier, nearest the 27MAV (1,187 lb) and the 25G and 30MAV (1,400 lb).
- Exterior height, 12 ft 2 in: lowest of twelve, level with the 17MAV, 22MAV and three others; next are the 21G, 25G and four others (12 ft 4 in).
- Black tank, 37 gal: smallest of twelve, level with the 17MAV, 22MAV and three others; next are the 21G, 25G and three others (39 gal).
Next to the 22MAV, the nearest lighter floorplan by dry weight, the 24MAV is 750 lb heavier by dry weight, has a GVWR 1,050 lb higher, has a tongue weight 257 lb heavier, is 3 ft 5 in longer and sleeps two fewer; the two publish the same exterior height, interior height, fresh tank, grey tank and black tank.
Next to the 27MAV, the nearest heavier floorplan by dry weight, the 24MAV is 250 lb lighter by dry weight, has a tongue weight 13 lb heavier, is 2 ft 3 in shorter and sleeps three fewer; the two publish the same GVWR, exterior height, interior height, fresh tank, grey tank and black tank.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (11,000 lb) and the upper loaded tongue estimate (1,650 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published figure, because loaded is never lighter than that.
03 The Momentum floorplan family
Momentum is Grand Design's toy-hauler family, and it spans four rosters across both tow types. The full-size Momentum fifth wheel is the flagship — a 101-inch wide-body coach on MORryde independent suspension with disc brakes, carrying a 60-gallon dual fuel station. The Momentum G-Class fifth wheel sits below it on MORryde CRE3000 suspension and a Rotoflex pin box with a 30-gallon fuel station, and the G-Class travel trailer puts that same garage behind a bumper pull. The Momentum MAV is the compact end — the lightest and cheapest way into a Momentum garage, and the one roster with no fuel station at all. The 24MAV on this page is highlighted; each other profiled plan links to its own page. The full MY2027 catalogue runs to 28 floorplans across the four rosters; eight are profiled in depth here and the rest are catalogued on the line hub with their weights.
| Floorplan | Roster | Type | Length | Garage | Sleeps | Notable |
|---|---|---|---|---|---|---|
| 17MAV | Momentum MAV | TT | 22′ 11″ | 11 ft 6 in | 2 | Lightest and cheapest Momentum built |
| 22MAV | Momentum MAV | TT | 26′ 6″ | 13 ft 6 in | 5 | 13 ft 6 in garage, sleeps 5 |
| 24MAV | Momentum MAV | TT | 29′ 11″ | 18 ft | 3 | 18 ft garage, sleeps 3 |
| 27MAV | Momentum MAV | TT | 32′ 2″ | 13 ft 6 in | 6 | 13 ft 6 in garage, sleeps 6 |
| 28MAV | Momentum MAV | TT | 33′ 11″ | 10 ft 4 in | 6 | Top of the MAV range — the only MAV with a slide-out |
| 30MAV | Momentum MAV | TT | 36′ 11″ | 11 ft | 6 | 11 ft garage, sleeps 6, 1 slide |
The Momentum MAV is the compact end of the family — the lightest, cheapest way into a Momentum garage, on a single-axle-to-tandem bumper-pull with a 24-inch DoveTail loading ramp. It is the one Momentum roster that does NOT carry a fuel station: Grand Design prints N/A into the Fuel Capacity field on all five MAV plans and omits the fuel bullet from the MAV feature list, so no fuel figure is shown here. Additional MAV floorplans are catalogued on the line hub.

11 NHTSA safety record
NHTSA holds 19 recall campaigns and 201 owner complaints (model years 2005 on) against the Momentum line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 201 complaints filed on this line the most-reported components are structure (41%), unknown or other (19%) and suspension (10%).
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Momentum line page.
