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 upper-trim sibling to the standard Fleetwood Frontier, built on the Freightliner Custom Chassis XCR platform with the Cummins ISB 6.7L diesel at 360 HP and 800 lb-ft of torque. MHSRV stocks one of the largest selections of new and used Fleetwood Frontier GTX motorhomes for sale in the country, all backed by industry-leading discount pricing.
The GTX steps up from the standard Frontier with triple 15,000 BTU A/C units, the AquaHot 400D hydronic heating system, a flat floor design front-to-rear, up to 190 cubic feet of pass-through basement storage, and the optional Corner Office workspace on the 37RT. Two floor plans (37RT and 39TA) sit at the upper end of the Frontier lineup for buyers who want more interior space, more cooling capacity, and more luxury features than the standard Frontier offers.
Chassis, Powertrain, and Towing
Every Frontier GTX is built on the Freightliner Custom Chassis XCR platform with the Freedom Sport configuration. The powertrain is the Cummins ISB 6.7L diesel (360 HP, 800 lb-ft torque at 1,600 RPM), paired with the Allison 3000 MH 6-speed automatic transmission and a Delco Remy 160-amp alternator.
The chassis carries the V-Series suspension with VFS front suspension, V-Ride stability technology, standard BrakeSync, and Vacu-Bond floors, walls, and ceilings with the Powerlock System II. Both floor plans share a 43,600-lb GCWR, a 10,000-lb hitch rating, a 1,000-lb tongue weight rating, and 100 gallons of fuel capacity.
Triple A/C and AquaHot 400D Climate System
Climate control is one of the GTX's biggest departures from the standard Frontier. Three 15,000 BTU A/C units with a rear heat pump provide more cooling capacity than the typical dual-A/C setup found on most Class A diesel pushers. That's particularly valuable for full-time travelers, southern-climate camping, and the longer 39TA floor plan where dual A/C may not cover front-to-rear.
The AquaHot 400D hydronic heating system handles space heating and hot water from a single diesel-fired unit, drawing fuel from the same chassis tank that powers the engine. Using diesel for all heating eliminates onboard propane entirely, so there is no propane tank, propane lines, or propane safety equipment on the coach.
Exterior and Storage
The exterior runs full-body paint (six paint schemes offered), a 20-foot patio awning on the 37RT or an 18-foot awning on the 39TA, and the wedged holding tank configuration that maximizes tank capacity within the chassis frame. Basement pass-through storage tops out at 190 cubic feet, notable for a coach in this segment.
Interior, Kitchen, and Bath
The interior runs a flat floor design front-to-rear, three décor packages, and three cabinetry finish options.
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.
Master Bedroom Configuration Varies by Plan
The 37RT uses an Encore Series king bed (72-by-80-inch) paired with a dual 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 Corner Office on the 37RT
The Corner Office is an optional workspace exclusive to the 37RT floor plan. It adds a desk with drawer, a lower hanging wardrobe, a bench with storage, an LED TV/monitor, and overhead shelving. The Corner Office is aimed at full-time travelers and remote workers who want a dedicated home-office space rather than working from the dinette or sofa.
Off-Grid and Connectivity
The optional Connectivity Package adds a 330-watt solar panel paired with the Wi-Fi Ranger Sky Pro LTE and a cellular booster. The package is available on both floor plans for buyers planning extended off-grid stays or full-time travel where campground Wi-Fi is unreliable.
The Two Frontier GTX Floor Plans
Motor Home Specialist stocks the Frontier GTX in two floor plans, both on the Freightliner XCR chassis with the Cummins 6.7L diesel.
37RT: 37 ft 11 in. 238-inch wheelbase. Encore Series king bed. Dual dresser configuration. Sofa sleeper with queen mattress. 38-by-30-inch shower with glass door. Optional Corner Office workspace. 211 cubic feet of interior storage.
39TA: 40 ft 3 in. 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, 196 cubic feet of exterior storage. Optional stackable washer and dryer.
Shopping the Frontier GTX? Compare it against the rest of the Fleetwood diesel pusher lineup: the standard Frontier (entry-tier with more floor plan options and lower entry price), the Discovery (mid-luxury tier above the Frontier GTX), or the Discovery LXE (Fleetwood's flagship diesel pusher). Buyers cross-shopping Class A gas alternatives can look at the Fleetwood Bounder or Flair. All are stocked at MHSRV.
Fleetwood Frontier GTX FAQs
What is the Fleetwood Frontier GTX?
The Frontier GTX is the upper-trim Class A diesel pusher in Fleetwood's Frontier lineup, built on the Freightliner Custom Chassis XCR platform with the Freedom Sport configuration. It carries 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, and the flat floor design front to rear. The GTX is offered in two floor plans (37RT and 39TA) from 37 ft 11 in to 40 ft 3 in.
What engine and chassis are on the Frontier GTX?
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 (360 horsepower, 800 lb-ft of torque at 1,600 RPM), paired with the Allison 3000 MH 6-speed automatic transmission. The chassis carries the V-Series suspension with VFS front suspension, V-Ride stability technology, standard BrakeSync, and Vacu-Bond floors, walls, and ceilings with the Powerlock System II.
What is the difference between the Frontier and the Frontier GTX?
Both are Fleetwood Class A diesel pushers on Freightliner Custom Chassis platforms with a Cummins 6.7L diesel and AquaHot hydronic heating. The standard Frontier is offered in three floor plans (33TL, 37S, 38RT) on the Freedom Sport (33TL) or Freedom Bridge (37S, 38RT) chassis. The Frontier GTX is the upper-trim sibling, offered in two floor plans (37RT, 39TA) on the Freedom Sport XCR chassis with the larger 360-HP Cummins. The GTX adds triple 15,000 BTU A/C units (vs dual on the Frontier), the AquaHot 400D across both plans (the Frontier 33TL uses the smaller AquaHot 250D), more interior storage, and the flat floor design. Pick the GTX for triple A/C cooling capacity, AquaHot 400D across the lineup, and the flat floor build. Pick the standard Frontier for the wider floor plan selection (including the smaller 33TL) and the lower entry price.
How much can the Frontier GTX tow?
The Frontier GTX carries 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.
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. That's particularly valuable for full-time travelers, southern-climate camping, and the longer 39TA floor plan where dual A/C may not adequately cover front to rear.
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. Using diesel for all heating eliminates onboard propane on the Frontier GTX entirely, removing the propane tank, propane lines, and propane safety equipment standard on most Class A motorhomes. The 400D provides more heat output and longer hot-water draw than the smaller AquaHot 250D used on entry-level 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 adds a desk with drawer, a lower hanging wardrobe, a bench with storage, an LED TV/monitor, and overhead shelving. The Corner Office is aimed at full-time travelers and remote workers who want a dedicated office space in the coach 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 ft 11 in, 238-in wheelbase, Encore Series king bedroom, sofa sleeper with queen mattress, 38-by-30-in fiberglass shower with glass door, dual dresser, optional Corner Office workspace, 211 cu ft interior storage). The 39TA (40 ft 3 in, 266-in wheelbase, Encore Series queen bedroom with suspended LED TV, Adap-Table dinette, 36-by-34-in shower, 174 cu ft interior storage, 196 cu ft exterior storage).
How does the Frontier GTX handle off-grid camping?
The optional Connectivity Package adds a 330-watt solar panel paired with the Wi-Fi Ranger Sky Pro LTE and a cellular booster. The package is available on both floor plans for buyers planning extended off-grid stays or full-time travel where campground Wi-Fi is unreliable. Combined with the AquaHot 400D handling heat and hot water from the diesel tank, the Frontier GTX has the systems in place for stretches away from shore power and pedestal water.
Do I need a CDL to drive a Fleetwood Frontier GTX?
In most states, no CDL is required to operate a Fleetwood Frontier GTX because it is a personal-use recreational vehicle. That said, CDL and non-commercial license requirements vary by state, particularly for motorhomes above certain weight or length thresholds. The Frontier GTX's 43,600-lb GCWR and 40-foot 39TA may trigger a non-commercial Class A or Class B license in some states, so buyers should check with their state's DMV before purchase.
