Holiday Rambler Endeavor RVs For Sale
Holiday Rambler Endeavor Class A diesel pusher motorhomes for sale at Motor Home Specialist, the #1 Volume Selling Motor Home Dealer in the World and the #1 Holiday Rambler RV dealer in the country. The Endeavor is Holiday Rambler's mid-tier Class A diesel pusher, built on the Freightliner Custom Chassis XCM platform with the Titan Bridge configuration and powered by 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 Endeavor motorhomes for sale in the country, all backed by industry-leading discount pricing.
The Endeavor sits between Holiday Rambler's entry-priced diesel pushers and the flagship Armada lineup. Like the Armada, it uses the Freightliner XCM Titan Bridge platform, but with a smaller Cummins 6.7L diesel and a more compact 38-to-40-foot footprint that targets buyers who want a luxury Class A diesel pusher in a more manageable length than the 40-to-44-foot flagship tier.
Standard equipment includes the AquaHot 400D hydronic heating system (eliminating onboard propane), heated polished porcelain tile flooring in the living area, residential appliances, the Wi-Fi Extender Pro Pack with LTE, Collision Mitigation by MobilEye, a 330-watt solar panel, and Apex Custom Furniture. Three floor plans (38K, 38N, and 38W) share the same chassis platform with different interior layouts. The 38K is new for 2027 and adds two full baths.
Chassis, Powertrain, and Towing
Every Holiday Rambler Endeavor is built on the Freightliner Custom Chassis XCM platform with the Titan Bridge configuration. The powertrain is the Cummins ISB 6.7L diesel (360 HP, 800 lb-ft torque), 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 standard tire pressure monitoring. Body construction uses Holiday Rambler's Vacu-Bond floors, walls, and ceiling with the Powerlock System, and a molded fiberglass roof for low-maintenance durability. The cab includes dual cockpit monitors for camera and navigation viewing.
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. Wheelbase varies: 252 inches on the 38N, 263 inches on the 38W.
AquaHot 400D Heating and Propane-Free Build
The AquaHot 400D hydronic heating system handles space heating, hot water, and engine pre-heat 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 coach entirely, so there is no propane tank, propane lines, or propane safety equipment.
The heated polished porcelain tile flooring in the living area is standard equipment across both floor plans and pairs with the AquaHot 400D system for radiant floor warmth.
Driver-Assist: Collision Mitigation by MobilEye
Collision Mitigation by MobilEye comes standard on every Holiday Rambler Endeavor, adding forward-collision warning and adaptive safety features on top of the chassis's V-Ride stability, BrakeSync, and tire pressure monitoring. That standard ADAS content is one of the mid-tier lineup's real differentiators against comparably priced Class A diesel pushers.
Interior, Kitchen, and Bath
The interior runs three décor packages, three cabinetry finish options (including a Toffee medium-walnut wood option), heated polished porcelain tile flooring in the living area, a standard fireplace on both floor plans, and the Firefly MultiPlex wiring system paired with a color touchscreen for centralized coach control.
The galley pairs a residential refrigerator with ice and water in the door, an induction cooktop, and a convection microwave as standard equipment. Both floor plans include a washer/dryer.
The bath uses a 50-by-28-inch shower with seat on the 38N (with a step-up entry) or a 38-by-30-inch shower on the 38W.
Master Bedroom and Sleeping
Both floor plans use an Encore Series king bed (72-by-80-inch) in the master paired with a wardrobe configuration. The 38N adds a 28-by-73-inch convertible bunk bed with barn doors as a flexible second-bedroom configuration; the 38W uses a more traditional couples-focused layout without bunk beds.
Off-Grid and Connectivity
The Wi-Fi Extender Pro Pack with LTE comes standard, paired with a cell booster, a 330-watt solar panel, and the Firefly Eclipse module that enables remote access to coach systems via a smartphone app over Wi-Fi. Combined with the AquaHot 400D handling heat and hot water from the diesel tank, the coach is set up for stretches away from shore power and campground Wi-Fi.
Exterior Build and Paint
The exterior runs a molded fiberglass roof, full-body paint (seven paint schemes offered), an 18-foot patio awning on both floor plans, and Holiday Rambler's Vacu-Bond body construction.
The Three Endeavor Floor Plans
Motor Home Specialist stocks the Endeavor in three floor plans, all on the Freightliner XCM Titan Bridge chassis with the Cummins 6.7L diesel.

Holiday Rambler Endeavor FAQs
What is the Holiday Rambler Endeavor?
The Holiday Rambler Endeavor is a mid-tier Class A diesel pusher motorhome built on the Freightliner Custom Chassis XCM platform with the Titan Bridge configuration. It carries the AquaHot 400D hydronic heating system (eliminating onboard propane), heated polished porcelain tile flooring in the living area, residential appliances, the Wi-Fi Extender Pro Pack with LTE, Collision Mitigation by MobilEye, and a 330-watt solar panel as standard equipment. It's offered in three floor plans (38K, 38N, and 38W) on a 252-inch or 263-inch wheelbase.
What engine and chassis are on the Endeavor?
The Holiday Rambler Endeavor is built on the Freightliner Custom Chassis XCM platform with the Titan Bridge configuration. Power comes from the Cummins ISB 6.7L diesel (360 HP, 800 lb-ft torque), 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 standard tire pressure monitoring. Titan Bridge is the exclusive Freightliner XCM configuration used across Holiday Rambler diesel pushers, so both the mid-tier Endeavor and the flagship Armada share the same core chassis platform.
What is the difference between the Endeavor and the Armada?
The Endeavor and Armada are both Holiday Rambler Class A diesel pushers built on the Freightliner XCM Titan Bridge platform with the AquaHot 400D hydronic heating system. The Armada is the flagship lineup with the larger Cummins L9 diesel (380 to 450 HP), four floor plans from 40 to 44 feet, and the option of an UltraSteer tag axle on the longer 44-foot configurations. The Endeavor is the mid-tier lineup with the smaller Cummins 6.7L diesel (360 HP), three floor plans at 38 to 40 feet (including the new 38K two-full-bath plan for 2027), and a single rear axle. Pick the Endeavor for luxury Class A diesel content in a more manageable 38-to-40-foot length at a more accessible price. Pick the Armada for the larger L9 engine, more floor plan choices, longer 40-to-44-foot options, and the tag axle on the flagship 44-foot plans.
How much can the Endeavor tow?
The Holiday Rambler Endeavor carries a 10,000-lb hitch rating with a 1,000-lb tongue weight rating across both floor plans. The GCWR is 43,600 pounds, sized for a small SUV, sedan, or compact tow vehicle. Always confirm tow vehicle weight against the coach's actual GCWR before towing.
What is the AquaHot 400D system?
The AquaHot 400D is a hydronic heating system that handles space heating, hot water, and engine pre-heat 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 coach entirely, removing the propane tank, propane lines, and propane safety equipment standard on most Class A motorhomes. On the Endeavor, the AquaHot 400D also feeds the standard heated polished porcelain tile flooring in the living area.
What driver-assist features come on the Endeavor?
Collision Mitigation by MobilEye is standard on every Holiday Rambler Endeavor, adding forward-collision warning and adaptive safety features on top of the chassis's V-Ride stability, BrakeSync, and tire pressure monitoring. Dual cockpit monitors display camera feeds and navigation. That standard ADAS content is one of the mid-tier lineup's real differentiators against comparably priced Class A diesel pushers.
Does the Endeavor have heated floors?
Yes. The Holiday Rambler Endeavor carries heated polished porcelain tile flooring in the living area as standard equipment on both floor plans. The heated tile system pairs with the AquaHot 400D hydronic system, drawing on the diesel-fired unit for warmth that doesn't require electrical resistance heating or onboard propane.
What floor plans does the Endeavor come in?
Motor Home Specialist stocks the Holiday Rambler Endeavor in three floor plans: the new 38K (added for 2027 with two full baths and sleeping capacity up to nine), the 38N (38 ft 8 in, 252-inch wheelbase, Encore Series king master with 28-by-73-inch convertible bunk bed behind barn doors, 50-by-28-inch shower with seat, sofa sleeper with twin mattress, 148 cu ft interior storage) and the 38W (40 ft 1 in, 263-inch wheelbase, Encore Series king master in a couples-focused layout, 38-by-30-inch shower, sofa sleeper with full mattress, 132 cu ft interior storage). Both share a 43,600-lb GCWR and an 18-foot patio awning.
How does the Endeavor handle off-grid camping?
Every Holiday Rambler Endeavor comes standard with a 330-watt solar panel, the Wi-Fi Extender Pro Pack with LTE, a cell booster, and the Firefly Eclipse module for remote coach-system access via a smartphone app over Wi-Fi. The AquaHot 400D handles heat and hot water from the diesel chassis tank rather than propane. Combined, the coach is set up for stretches away from shore power and campground Wi-Fi.
Do I need a CDL to drive a Holiday Rambler Endeavor?
In most states, no CDL is required to operate a Holiday Rambler Endeavor 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 43,600-lb GCWR 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.
