01 What makes it unique

The 3003RL is the payload Influence: a rear living area on dual opposing slides behind a center kitchen island, with a front bedroom (a queen bed slide and front wardrobe with washer/dryer prep), a free-standing dinette, theater seating opposite a fireplace and entertainment center, and a tri-fold sofa. At about 35 feet on three slides and a lower 12-foot-9 exterior height, it sleeps four. 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 an 18,000-pound GVWR against the 12,500-pound dry weight, leaving a 5,500-pound cargo capacity — the largest in the line by a wide margin — and a 2,300-pound dry pin. A 30,000-BTU air-conditioning rating and 83/106/53-gallon fresh/grey/black tanks are standard, with six-point auto-leveling available. At a starting MSRP around $114,808 — the lowest placard in the line — the 3003RL is the Influence for buyers who want to carry a lot of gear and water in a lower-profile rear-living coach, towed with a one-ton truck.

Towing it

Tow rating needed18,000 lb
Published dry pin weight2,300 lb
Loaded pin weight, rule of thumb2,700–4,500 lb
In-bed fifth-wheel hitch rating needed18,000 lb towed / 4,500 lb pin
Payload check. Budget loaded, not dry: subtract the loaded range, every passenger and the bed and cab load from the payload on your tow vehicle’s door-pillar placard (49 CFR 571.110 S4.3).

Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433).

03 The Influence floorplan family

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 3003RL on this page is highlighted.

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 Notes on this floorplan

Biggest cargo in the line

Its 5,500-pound CCC is far and away the largest Influence payload — genuine room for gear, water and a full family’s supplies.

Lower 12-foot-9 profile

A lower exterior height than the taller plans — easier in height-restricted spots and a lower center of gravity.

Rear living, dual opposing slides

A wide rear living area on two opposing slides behind a center island kitchen, with washer/dryer prep up front.

Wants a one-ton truck

An 18,000-pound-GVWR full-profile fifth wheel — confirm a properly rated one-ton truck’s payload and rear-axle rating.

05 How it compares

↔ Cross-shop
Keystone Montana (rear-living)

Keystone’s luxury Montana — a full-profile rear-living cross-shop in the same tier.

← Lighter pin
Influence 2903RL

The 2903RL — the same rear-living format, shorter and lighter with a smaller cargo capacity.

↑ Step up
Grand Design Solitude

The flagship Solitude on the same platform — more length and luxury above the Influence.

06 Loading it for a trip

A full 83-gallon fresh tank is about 692 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 13% of the 3003RL’s 5,500 lb cargo capacity, leaving 4,808 lb (1,202 lb per rated berth). Across 7 Influence floorplans the water share runs 13% to 34%, and this plan’s is the lowest. Nearest on that share: Influence 3804DS at 16%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
