2025 Grand Influence for Sale

The Influence is Grand Design's newest fifth-wheel line, slotted just below the Solitude as a way to get much of that flagship's space and finish at a friendlier price. Grand Design positions it as having the room of a Solitude in a more affordable package, with taller ceilings, bigger cabinets, and a sweeping scenic front window. Floor plans run roughly 34 to 43 feet on an 18,000-19,000-lb GVWR chassis with dual axles, covering rear-living, mid-kitchen, and bunkhouse layouts. Because it is a recent introduction, used inventory under the Influence name is still thin, so most shoppers will be looking at near-new units. For buyers who want full-size fifth-wheel living and Grand Design's strong floor-plan reputation but do not need the very top Solitude trim, the Influence is the sensible middle of the fifth-wheel range.
