2026 Grand Design Influence3904BH

The 3904BH is the top of the Influence bunkhouse range: a private bunkhouse sleeping five, an outdoor kitchen (griddle, sink and beverage cooler), a U-shaped dinette, dual entry doors (one into a half bath for a bath-and-a-half) and quad slides in a widebody layout, with theater seating and a front private bedroom — the whole coach sleeping nine, the most in the line. Dual opposing living slides open a wide main level. The equipment is the standard Influence package — a 16-cubic-foot 12-volt refrigerator, gel-coat sidewalls and the 330-watt Influence Solar Package — on the 101-inch wide-body platform inside a five-sided welded-aluminum cage, under a walk-on Thermal Roof, with a fully enclosed, heated underbelly.

Grand Design publishes a 19,000-pound GVWR against the 16,000-pound dry weight — the heaviest in the line — leaving a 3,000-pound cargo capacity and a 2,700-pound dry pin. A 30,000-BTU air-conditioning rating and 83/106/106-gallon fresh/grey/black tanks are standard, with six-point auto-leveling available. RVUSA does not carry a starting MSRP for the 3904BH; dealers list it in the mid-to-high $130,000s. It is the Influence for large families who want a private bunkhouse, an outdoor kitchen and a bath-and-a-half in the longest coach in the line, towed with a one-ton truck.

Influence is Grand Design's residential-style full-profile fifth wheel on the 101-inch wide-body platform that underpins the flagship Solitude, offered at a lower entry point — a cross-shop against Keystone's Cougar and Montana, Jayco's Eagle and North Point, with the Grand Design Reflection a step below. The 2026 line runs to seven floorplans, all profiled in full and linked below. The 3904BH on this page is highlighted.
