2027 Grand Design Momentum G-Class25G

The Momentum G-Class 25G is a travel-trailer toy hauler 30 ft 11 in long with a 13 ft 6 in garage, on two axles with two slide-outs and a 30-gallon fuel station. It is on Grand Design’s Momentum G-Class roster for 2027.

Grand Design’s page lists an unloaded vehicle weight of 8,600 lb, a GVWR of 13,000 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, 78 gal grey and 39 gal black, and it sleeps 6.

Grand Design’s page names the 27G and 29GS as comparison floorplans.

How the 25G 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.

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 25G 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.

Closest sibling: the Momentum 27G, nearest on the published figures. It differs on 3 of the 8 fields both publish (this plan first): length 30 ft 11 in vs 32 ft 3 in; dry weight 8,600 lb vs 8,650 lb; hitch weight 1,400 lb vs 1,500 lb. They match on sleeps, GVWR, fresh tank, grey tank and black tank.

Either side of it by GVWR: Momentum 30MAV is 1,000 lb lighter (12,000 lb GVWR); Momentum 27G matches it at 13,000 lb GVWR.

All 24 Momentum floorplans: Momentum line hub.
