01 What Influence is
Influence is Grand Design's residential-style full-profile fifth wheel — the same 101-inch wide-body platform that underpins the flagship Solitude, offered at a lower entry point. Grand Design, based in Middlebury, Indiana and a Winnebago Industries company since 2016, positions Influence in the heart of the full-profile market: above the half-ton-plus Reflection and against Keystone's Cougar and Montana and Jayco's Eagle and North Point. These are residential layouts for full-timers and serious travelers towing a properly rated three-quarter-ton or one-ton truck.
The build is genuine full-profile construction. Every Influence rides the 101-inch wide-body platform inside a five-sided welded-aluminum cage, under a walkable Thermal Roof (R-40, fiberglass and radiant foil over a full-length vented attic), with fully laminated R-11 walls (welded-aluminum framed over rigid foam), a triple-insulated R-45 main floor and a fully enclosed, heated all-weather underbelly with heated tanks and storage. The sidewalls are gel-coated. Six-point hydraulic auto-leveling is available.
The systems package is strong for the tier. A 16-cubic-foot 12-volt refrigerator that runs off battery and solar, the 330-watt Influence Solar Package with a controller and inverter prep, and — plan-dependent — a fireplace, theater seating, a 40-inch TV and a free-standing dinette come standard, with a third air conditioner with heat pump available. For 2026 the line runs to seven floorplans, all profiled in depth below — from the sub-35-foot rear-living 2903RL to the dual-suite 3804DS and the outdoor-kitchen bunkhouse 3904BH.
02 Floorplans profiled in depth
All seven 2026 Influence floorplans are profiled in full with RVUSA-verified specifications, spanning the line from the shortest rear-living couples coach to the dual-suite and outdoor-kitchen bunkhouse flagships: two rear-living plans, two rear-galley-kitchen plans, a family bunkhouse, a two-master dual-suite and the outdoor-kitchen 3904BH.
| Floorplan | Dry wt | Length | Sleeps | Layout | MSRP |
|---|---|---|---|---|---|
| 2903RL | 11,800 lbs | 34' 5" | 4 | Rear living, walk-around island, front master — shortest, lightest, lightest pin | $116,780 |
| 3003RL | 12,500 lbs | 34' 11" | 4 | Rear living, dual opposing slides, center island — biggest payload, lower profile | $114,808 |
| 3203GK | 12,712 lbs | 35' 11" | 3 | Rear galley kitchen, private front bedroom — couples, kitchen across the back | $116,093 |
| 3503GK | 13,868 lbs | 38' 3" | 4 | Rear galley kitchen, private front bedroom — stretched for more living space | $116,247 |
| 3704BH | 14,798 lbs | 40' 4" | 8 | Private rear bunk room, front bedroom, quad slides — family, tightest cargo | $119,459 |
| 3804DS | 14,603 lbs | 42' 6" | 6 | Two masters, two full baths, loft, quad slides — dual-suite, heaviest pin | $126,331 |
| 3904BH | 16,000 lbs | 42' 8" | 9 | Bunkhouse + outdoor kitchen + bath-and-a-half, quad slides — longest, sleeps nine | — |
Body specifications (lengths, exterior heights, width, tanks, sleeping, slides and awnings) are verified against the RVUSA structured records for the 2026 Influence roster. Dry weight (UVW), GVWR, payload (CCC) and pin (hitch) weight are published per plan, and for every plan the base dry weight plus payload equals the GVWR exactly — so all weight figures are shown unflagged with no derivation. RVUSA's interior-height field is not published consistently for this line and is omitted on the plan pages; a Chassis row is shown instead. MSRP figures are starting MSRP; dealer (street) pricing runs below placard, and the 3904BH carries no RVUSA starting price (dealer-typical noted on its page). Real loaded pin weights run higher — weigh the loaded coach and confirm against your truck's payload and rear-axle ratings.
03 How to choose
The Influence line sorts by layout, length and how much pin and payload your truck can carry. For the shortest, most maneuverable luxury coach, the 2903RL puts a rear living area behind a walk-around island kitchen with a front master, keeping the whole rig under 35 feet on the line's lightest 2,190-pound pin — the easiest Influence to match to a three-quarter-ton truck. For the most cargo, the 3003RL pairs a lower 12-foot-9 profile with a 5,500-pound payload — by far the largest in the line — on a rear-living, dual-opposing-slide layout.
For a rear kitchen, the 3203GK runs a residential galley across the back with a private front bedroom, and the 3503GK is the same format stretched for more living space. For families, the 3704BH is a widebody bunkhouse with a private rear bunk room sleeping eight (on the line's tightest 2,002-pound cargo margin), and the 3904BH is the longest coach in the line — a private bunkhouse with an outdoor kitchen and a bath-and-a-half, sleeping nine. For two private suites, the 3804DS carries two master bedrooms, two full baths and a loft.
Across all of them the build is identical: the 101-inch wide-body platform, the five-sided welded-aluminum cage, the walk-on Thermal Roof, the fully enclosed heated underbelly, the 16-cubic-foot 12-volt refrigerator and the 330-watt Influence Solar Package. The decision is layout, length, weight and pin — and how many the plan sleeps. Above Influence on the same platform sits the flagship Solitude; below it, the lighter Reflection.
04 What to weigh before buying
This is the Solitude platform at a lower entry point
Influence rides the same 101-inch wide-body platform as Grand Design's flagship Solitude, positioned a tier below it on price and above the half-ton-plus Reflection. Its case is genuine full-profile construction — a five-sided welded-aluminum cage, a walk-on Thermal Roof (R-40), fully laminated R-11 walls, a triple-insulated R-45 main floor and a fully enclosed, heated all-weather underbelly — plus a strong standard package (a 16-cubic-foot 12-volt refrigerator and the 330-watt Influence Solar Package) from a Winnebago Industries company. Cross-shop it against Keystone's Cougar and Montana and Jayco's Eagle and North Point on layout, weight and how each maker's standard equipment compares.
A 16-cu-ft 12V fridge and 330-watt solar are standard — A/C varies by plan
Every 2026 Influence ships with a 16-cubic-foot 12-volt refrigerator that runs off battery and solar, the 330-watt Influence Solar Package with a controller and inverter prep, a walk-on Thermal Roof and the fully enclosed heated underbelly — well cooled and largely off-grid-ready out of the box. Air conditioning is where the plans differ: four carry a single 15,000-BTU unit, while the 3003RL, 3804DS and 3904BH carry a 30,000-BTU rating (a two-unit configuration). A third air conditioner with heat pump and six-point hydraulic auto-leveling are available. Factor the standard solar, the 12-volt fridge and the per-plan air-conditioning against a comparably equipped Cougar, Montana or Eagle, where a second air conditioner, larger solar or an inverter can be upcharges.
Match the truck honestly — these are full-profile coaches
Influence is a full-size fifth wheel. The plans run from 11,800 to 16,000 pounds dry on GVWRs of 15,000 to 19,000 pounds. Dry pins run from 2,190 pounds on the 2903RL to 2,911 pounds on the 3804DS — and real loaded pins run higher. The 15,000-pound-GVWR 2903RL suits a properly rated three-quarter-ton or one-ton truck; the 18,000- and 19,000-pound plans are firmly one-ton territory. The family 3704BH pairs a modest GVWR with the line's tightest 2,002-pound cargo margin, so load it carefully. The truck's payload and rear-axle rating, not just the hitch, are what matter — treat brochure pin weights as a floor, weigh the loaded coach, and confirm against your truck's door-jamb ratings before buying.
