Detailed Comparison

Shopping for an RV and torn between the 2024 Grand Design Momentum G-Class 21G and the 2024 Forest River Vengeance Rogue 29KS? We've put together a detailed spec comparison to help you decide.

The Grand Design Momentum G-Class 21G measures 44.0 ft in length at 10,500 lbs, compared to the Forest River Vengeance Rogue 29KS's 43.0 ft and 13,500 lbs. GVWR ratings sit at 13,300 lbs and 15,700 lbs respectively.

Capacity-wise, expect to sleep 9 in the Grand Design Momentum G-Class 21G versus 7 in the Forest River Vengeance Rogue 29KS. With 3 and 2 slide-outs respectively, the parked floor plans differ significantly.

Tank capacities are a key off-grid consideration. The Grand Design Momentum G-Class 21G carries 56 gal of fresh water, 58 gal gray, and 36 gal black. The Forest River Vengeance Rogue 29KS offers 84 gal fresh, 77 gal gray, and 43 gal black. The Forest River Vengeance Rogue 29KS has the edge for extended dry camping.

Budget-wise, the Grand Design Momentum G-Class 21G is listed at $77,000 compared to $80,000 for the Forest River Vengeance Rogue 29KS.

For family camping trips, the larger floor plan and additional berths make a real difference. For boondocking, the model with superior solar and battery setup will keep you comfortable off the grid longer. If you're going full-time, the larger tanks and more robust build quality matter enormously.

Take these specs as a starting point, then go see them in person — there's no substitute for stepping inside.
