Fleetwood Frontier GTX RVs For Sale
Fleetwood Frontier GTX Class A diesel pusher motorhomes for sale at Motor Home Specialist, the #1 Volume Selling Motor Home Dealer in the World and the #1 Fleetwood RV dealer in the country.
The Frontier GTX is the higher-trim sibling of Fleetwood's Frontier Class A diesel pusher, sharing the same Freightliner® Custom Chassis Freedom Sport platform but stepping up to a more capable feature set. The GTX includes triple 15,000 BTU A/C units with rear heat pump, the AquaHot® 400D hydronic heating system (eliminating onboard propane), the wedged holding tank configuration, the flat floor design front to rear, cavernous basement storage of up to 190 cubic feet with full pass-through configuration, and the optional Corner Office™ workspace on the 37RT. The Frontier GTX is offered in two floor plans (37RT and 39TA) at the upper end of the Frontier lineup, geared toward buyers who want more interior space, more A/C capacity, and more luxury features than the standard Frontier delivers.
The Frontier GTX is built on the Freightliner Custom Chassis XCR platform with the Freedom Sport configuration. Power comes from the Cummins® ISB 6.7L diesel rated at 360 horsepower and 800 lb-ft of torque (at 1,600 RPM), paired with the Allison 3000 MH 6-speed automatic transmission. A Delco Remy 160-amp alternator handles charging. The chassis includes the V-Series suspension system with the VFS front suspension, V-Ride™ technology for enhanced stability, and standard BrakeSync. Vacu-Bond™ floors, walls, and ceilings with the Powerlock System™ II handle body construction.
Chassis weight ratings are consistent across both floor plans: a 12,600-pound front GAWR, a 21,000-pound rear GAWR, a 43,600-pound GCWR, a 10,000-pound hitch rating, a 1,000-pound tongue weight rating, and 100 gallons of fuel capacity. Wheelbase varies: the 37RT uses a 238-inch wheelbase, while the 39TA uses a longer 266-inch wheelbase. Holding tank capacities are 95 gallons fresh, 65 gallons gray, and 45 gallons black across both floor plans, using the wedged tank configuration that maximizes capacity within the chassis frame.
Climate control runs three 15,000 BTU A/C units with a rear heat pump, paired with the AquaHot 400D hydronic heating system. The triple A/C configuration provides more cooling capacity than the typical dual-A/C setup found on most Class A diesel pushers, which is particularly valuable for full-time travelers and southern-climate camping. The AquaHot 400D handles space heating and hot water from a single diesel-fired unit, eliminating the need for any onboard propane.
The galley pairs a residential refrigerator with an induction cooktop and a convection microwave as standard equipment. The bath uses a 38-by-30-inch fiberglass shower with glass door on the 37RT and a 36-by-34-inch shower on the 39TA.
The bedroom configuration varies by floor plan. The 37RT uses an Encore Series king bed (72-by-80-inch) paired with the dresser configuration, dual fireplace, and CPAP storage. The 39TA uses an Encore Series queen bed (60-by-75-inch) paired with a suspended LED TV configuration, the Adap-Table® dinette, and a galley pull-out.
The 37RT includes The Corner Office™ as an optional configuration that adds a desk with drawer, a lower hanging wardrobe, a bench with storage, an LED TV/monitor, and overhead shelving. This makes the 37RT well-suited for full-time travelers and remote workers who want a dedicated home-office workspace in the coach.
The Frontier GTX is offered in three décor packages: Cadet (taupe sofa with blue art accents, marble countertops, gray tufted backsplash), Sand Castle (camel sofa with white quilted accent, light wood flooring, hexagon backsplash), and Silvercreek (charcoal sofa with faux fur accent, light wood flooring, gray subway tile backsplash). Cabinetry is available in three finish options: Winter Fog (white), Roasted Almond (medium walnut-gray), and Sedona (charcoal slate).
The Frontier GTX is available in six exterior paint schemes, all new for the 2025 model year: Matador, Pioneer, River Bed, Stage Coach, Sundance, and Tomahawk.
At MHSRV, the Frontier GTX is offered in two floor plans: the 37RT and the 39TA. The 37RT is 37 feet 11 inches long with a 238-inch wheelbase and uses the Encore Series king bedroom paired with a sofa sleeper with queen mattress, a 32-inch LED TV with fireplace, the 38-by-30-inch fiberglass shower with glass door, the dual dresser configuration with pull-out hamper, the optional Corner Office workspace, the optional Hide-A-Loft™ Electric Drop Down Bed with LED TV, optional power theater seating, and 211 cubic feet of interior storage. The 39TA is 40 feet 3 inches long with a 266-inch wheelbase and uses the Encore Series queen bedroom paired with the suspended LED TV configuration, the Adap-Table dinette, the optional stackable washer/dryer, the 36-by-34-inch shower, the optional Hide-A-Loft Electric Drop Down Bed with LED TV, optional power theater seating, and 174 cubic feet of interior storage with 196 cubic feet of exterior storage. Both floor plans share a 12-foot 10-inch overall height, 102-inch overall width, 84-inch interior height, 96-inch interior width, 95-gallon fresh water capacity, 65-gallon gray water, and 45-gallon black water tanks.

Fleetwood Frontier GTX FAQs
What is the Fleetwood Frontier GTX?
The Frontier GTX is the higher-trim Class A diesel pusher in Fleetwood's Frontier lineup, built on the Freightliner Custom Chassis XCR platform with the Freedom Sport configuration. It includes triple 15,000 BTU A/C units with rear heat pump, the AquaHot 400D hydronic heating system (eliminating onboard propane), the wedged holding tank configuration with up to 190 cubic feet of basement storage, the flat floor design front to rear, and the optional Corner Office workspace configuration on the 37RT. It's offered in two floor plans (37RT and 39TA) ranging from 37 feet 11 inches to 40 feet 3 inches long.
What chassis is the Frontier GTX built on?
The Frontier GTX is built on the Freightliner Custom Chassis XCR platform with the Freedom Sport configuration. Power comes from the Cummins ISB 6.7L diesel rated at 360 horsepower and 800 lb-ft of torque (at 1,600 RPM), paired with the Allison 3000 MH 6-speed automatic transmission. The chassis includes the V-Series suspension with the VFS front suspension, V-Ride technology for enhanced stability, and standard BrakeSync. Vacu-Bond floors, walls, and ceilings with the Powerlock System II handle body construction.
What's the difference between the Frontier and the Frontier GTX?
Both the Frontier and the Frontier GTX are Fleetwood Class A diesel pushers built on Freightliner Custom Chassis platforms with the Cummins 6.7L diesel and the AquaHot hydronic heating system. The standard Frontier is offered in three floor plans (33TL, 37S, 38RT) on either the Freedom Sport (33TL) or Freedom Bridge (37S, 38RT) chassis configurations. The Frontier GTX is the higher-trim sibling, offered in two floor plans (37RT, 39TA) on the Freedom Sport XCR chassis with the larger 360-horsepower Cummins. The GTX adds triple 15,000 BTU A/C units (vs. dual A/C on the standard Frontier), the AquaHot 400D system across both floor plans (the standard Frontier 33TL uses the smaller AquaHot 250D), more interior storage capacity, and the flat floor design front to rear. The Frontier GTX is geared toward buyers who want a more capable, longer-floor-plan diesel pusher with extra cooling capacity and luxury features. Floor plans, finish packages, and feature differences vary, and your salesperson can walk through the specific differences.
How much can the Frontier GTX tow?
The Frontier GTX has a 10,000-pound hitch rating with a 1,000-pound tongue weight rating across both floor plans. The GCWR is 43,600 pounds. Always confirm tow vehicle weight against the coach's actual GCWR before towing.
Is the Frontier GTX a diesel pusher?
Yes, the Frontier GTX is a Class A diesel pusher motorhome. The Cummins 6.7L diesel is mounted at the rear of the chassis (the "pusher" configuration), separating it from a Class A gas motorhome (with the engine at the front) or a Super C diesel (with the engine at the front of a truck-cab chassis).
How many A/C units does the Frontier GTX have?
The Frontier GTX comes standard with three 15,000 BTU A/C units paired with a rear heat pump. The triple A/C configuration provides more cooling capacity than the typical dual-A/C setup found on most Class A diesel pushers, which is particularly valuable for full-time travelers, southern-climate camping, and longer floor plans where dual A/C may not provide adequate coverage from front to rear of the coach.
What is the AquaHot 400D system?
The AquaHot 400D is a hydronic heating system that handles space heating and hot water from a single diesel-fired unit, drawing fuel from the same chassis tank that powers the engine. By using diesel for all heating functions, the AquaHot 400D eliminates the need for onboard propane on the Frontier GTX entirely, removing the propane tank, propane lines, and propane safety equipment that's standard on most Class A motorhomes. The 400D model provides more heat output and longer hot-water draw than the smaller AquaHot 250D used on entry diesel pushers.
What is The Corner Office on the 37RT?
The Corner Office is an optional workspace configuration available exclusively on the 37RT floor plan. It includes a desk with drawer, a lower hanging wardrobe, a bench with storage, an LED TV/monitor, and overhead shelving. The Corner Office is geared toward full-time travelers and remote workers who want a dedicated office space in their motorhome rather than working from the dinette or sofa.
What floor plans does the Frontier GTX come in?
Motor Home Specialist offers the Frontier GTX in two floor plans. The 37RT (37 feet 11 inches, 238-inch wheelbase, Encore Series king bedroom, sofa sleeper with queen mattress, 38-by-30-inch fiberglass shower with glass door, dual dresser configuration, optional Corner Office workspace, 211 cubic feet of interior storage). The 39TA (40 feet 3 inches, 266-inch wheelbase, Encore Series queen bedroom with suspended LED TV, Adap-Table dinette, 36-by-34-inch shower, 174 cubic feet of interior storage with 196 cubic feet of exterior storage).
Does the Frontier GTX come with a washer and dryer?
A washer and dryer is available as an optional upgrade on both Frontier GTX floor plans. The 37RT uses an optional side-by-side washer and dryer configuration. The 39TA uses an optional stackable washer and dryer to fit the layout.
Does the Frontier GTX come with solar?
The optional Connectivity Package adds a 330-watt solar panel as part of the upgrade (paired with Wi-Fi Ranger Sky Pro with LTE and a cellular booster). The package is available on both floor plans.
What décor and cabinetry options does the Frontier GTX offer?
The Frontier GTX is offered in three décor packages: Cadet (taupe sofa with blue art accents, marble countertops, gray tufted backsplash), Sand Castle (camel sofa with white quilted accent, light wood flooring, hexagon backsplash), and Silvercreek (charcoal sofa with faux fur accent, light wood flooring, gray subway tile backsplash).
