A comparison of what the current evidence supports, not a winner chosen from incomplete data.
Choose different modelsGrand Design documents ten 2026 Solitude floor plans, while Keystone documents three current 2027 Montana floor plans. Compare individual layouts because model years, dimensions, weights, and tank capacities vary.
Use the same model year and a similar floor-plan purpose when comparing weights, capacities, prices, and towing requirements. Open each model record to see the available manufacturer source and any limits in the published data.
