01 What makes it unique
The Momentum MAV 30MAV is a travel-trailer toy hauler 36 ft 11 in long with an 11 ft garage, on two axles with one 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 8,400 lb, a GVWR of 12,000 lb and a tongue weight of 1,400 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 6.
Grand Design’s page names the 27MAV and 28MAV as comparison floorplans.
How the 30MAV 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.
- Length, 36 ft 11 in: longest of twelve; next is the 31G (35 ft 11 in).
- Tongue weight as a share of dry weight, 16.7%: fourth-largest of twelve, between the 25G (16.3%) and the 27MAV (17.2%).
- Dry weight, 8,400 lb: sixth-heaviest of twelve, between the 28MAV (8,300 lb) and the 25G (8,600 lb).
- GVWR, 12,000 lb: sixth-highest of twelve, between the 21G, 24MAV and two others (11,000 lb) and the 25G, 27G and three others (13,000 lb).
- Slide-out count, 1: fewest of eight, level with the 21G, 27G and 28MAV; next are the 25G, 29GS and two others (2).
- Tongue weight, 1,400 lb: shared with the 25G; of twelve, six lighter and four heavier, nearest the 24MAV and 28MAV (1,200 lb) and the 30G (1,425 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 28MAV, the nearest lighter floorplan by dry weight, the 30MAV is 100 lb heavier by dry weight, has a GVWR 1,000 lb higher, has a tongue weight 200 lb heavier and is 3 ft longer; the two publish the same exterior height, fresh tank, grey tank, black tank, sleeping capacity and slide-out count.
Next to the 25G, the nearest heavier floorplan by dry weight, the 30MAV is 200 lb lighter by dry weight, has a GVWR 1,000 lb lower, is 6 ft longer, stands 2 in lower, has a grey tank 4 gal smaller, has a black tank 2 gal smaller and has one fewer slide-out; the two publish the same tongue weight, fresh tank and sleeping capacity.

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 (12,000 lb) and the upper loaded tongue estimate (1,800 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 30MAV 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.
