01 What makes it unique
The 3804DS is the dual-suite Influence: a front master with a queen bed slide and a private dual-entry bath, a second rear master with a folding queen bed slide, a full rear bath and a loft above — two masters and two full baths in one coach. Dual opposing living slides and an L-shaped sofa open the main level, and it runs four slide-outs at about 42½ feet, sleeping six. 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 14,603-pound dry weight, leaving a 4,397-pound cargo capacity and a 2,911-pound dry pin — the heaviest pin in the line. A 30,000-BTU air-conditioning rating and 83/106/106-gallon fresh/grey/black tanks are standard, with six-point auto-leveling available. At a starting MSRP around $126,331, with street pricing below placard, the 3804DS is the Influence for buyers who need two private bedroom suites and two full baths — multi-generation families or guests — in a luxury full-profile coach, towed with a one-ton truck.

Influence is Grand Design's residential-style full-profile fifth wheel — the 101-inch wide-body platform that underpins the flagship Solitude, offered at a lower entry point. The 2026 line runs to seven floorplans, all profiled here in full. Every Influence rides the 101-inch wide-body platform inside a five-sided welded-aluminum cage, under a walk-on Thermal Roof (R-40, fiberglass and radiant foil over a vented attic), with fully laminated R-11 walls, a triple-insulated R-45 main floor and a fully enclosed, heated all-weather underbelly with heated tanks. The Influence Solar Package — a 330-watt panel with controller and inverter prep — a 16-cubic-foot 12-volt refrigerator and gel-coat sidewalls are standard, with six-point hydraulic auto-leveling and a third air conditioner with heat pump available. Dry weight, GVWR, CCC and pin are published per plan and each plan's dry weight plus CCC equals its GVWR exactly. Real loaded pin weights run higher — always weigh the loaded coach and confirm against your truck's payload and rear-axle ratings.
04 What owners & reviewers report
Two masters, two full baths
A front master with a private dual-entry bath and a second rear master with a full rear bath and a loft above — genuine two-suite living.
Generous cargo and holding
A 4,397-pound CCC and 106-gallon grey and black tanks support a full household on longer stays.
Heaviest pin in the line
At a 2,911-pound dry pin and a 19,000-pound GVWR it is the heaviest-hitching Influence — real loaded pin runs higher.
Wants a one-ton truck
A 19,000-pound-GVWR quad-slide fifth wheel — confirm a properly rated one-ton truck’s payload and rear-axle rating.
05 How it compares
Keystone’s luxury Montana in a multi-bedroom layout — a comparable dual-suite cross-shop.
The 3704BH bunkhouse — lighter, with a rear bunk room instead of a second master suite.
The flagship Solitude on the same platform — the top of the Grand Design full-profile range.
