2027 Grand Design Momentum G-Class29GS

The Momentum G-Class 29GS is a travel-trailer toy hauler 34 ft 6 in long with an 11 ft* 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 9,720 lb, a GVWR of 13,000 lb and a tongue weight of 1,500 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 31G as comparison floorplans.

How the 29GS 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, 15.4%: third-smallest of twelve, between the 21G and 28MAV (14.5%) and the 30G (15.6%).

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 29GS 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 2 of the 8 fields both publish (this plan first): length 34 ft 6 in vs 32 ft 3 in; dry weight 9,720 lb vs 8,650 lb. They match on sleeps, GVWR, hitch weight, fresh tank, grey tank and black tank.

Either side of it by GVWR: Momentum 27G matches it at 13,000 lb GVWR; Momentum 30G matches it at 13,000 lb GVWR.

All 24 Momentum floorplans: Momentum line hub.
