INTRODUCTION

The 2004 Prowler 365BS is a fifth-wheel travel trailer manufactured by Fleetwood RV under the long-standing Prowler brand. Designed for extended stays and family travel, the 365BS stands out for its spacious bunkhouse layout, multiple slide-outs, and residential-style amenities. As a staple of early 2000s RV travel, this model appealed to buyers seeking comfort, practicality, and the ability to sleep large groups on the go.

HISTORY & ORIGINS

The Prowler brand dates back to the late 1960s, established by Fleetwood Enterprises as one of their most successful travel trailer lines. By 2004, Prowler had evolved into a well-regarded series offering both conventional tow-behind and fifth-wheel units. The 365BS (Bunk Slide) configuration was introduced to cater to larger families or groups, with a bunkhouse setup that became increasingly popular in early 2000s RV trends.

Fleetwood continued producing Prowler units until the brand was briefly discontinued in the mid-2000s, later revived by Heartland RV in a new incarnation.

ENGINE & PERFORMANCE OPTIONS

As a towable fifth-wheel RV, the 2004 Prowler 365BS does not include an engine. Performance is instead determined by:

• Dry weight: Approximately 11,000–11,800 lbs.

• Gross Vehicle Weight Rating (GVWR): ~13,000 lbs.

• Pin weight: Around 2,000–2,200 lbs.

• Hitch type: 5th wheel hitch compatible with most full-size pickup trucks.

• Axle configuration: Tandem axles with electric brakes.

Towing performance depends heavily on the capability of the tow vehicle (typically a 3/4-ton or 1-ton pickup).

DESIGN & FEATURES

The 2004 Prowler 365BS was designed with family comfort and spacious living in mind:

• Length: Approximately 38 feet.

• Triple slide-outs: Living room, master bedroom, and bunk area for expanded interior.

• Bunkhouse layout: Rear section includes bunk beds with privacy curtain.

• Sleeping capacity: Up to 8 people with bunks, convertible dinette, sofa bed, and queen master bed.

• Interior finish: Light wood cabinetry, linoleum/vinyl flooring with carpeted living areas.

• Full kitchen: Three-burner stove, oven, microwave, 8 cu ft refrigerator.

• Bathroom: Separate shower, sink, and toilet compartments.

The living area was designed to feel like a home away from home, ideal for seasonal use or long-haul travel.

TRIM LEVELS & VARIANTS

The 365BS floorplan was a specific configuration in the Prowler lineup, with minimal sub-trim variation. However, options and packages allowed customization:

• Interior décor packages: Offered in a few color schemes (earth tones, florals, etc.).

• Optional equipment included:

  • Upgraded insulation package

  • Awning

  • Ceiling fan

  • Larger freshwater/gray/black tanks

  • Roof-mounted air conditioning

  • Generator prep

Though not split into trims like automotive models, these packages allowed modest configuration flexibility.

SAFETY & TECHNOLOGY

Standard safety and tech features for the 2004 Prowler 365BS included:

• Dual propane tanks with automatic switchover.

• Smoke, CO, and LP gas detectors.

• Electric brakes on all wheels.

• Breakaway switch for hitch separation scenarios.

• 12V and 110V systems for off-grid and campground compatibility.

• Optional entertainment system: AM/FM/CD player with ceiling speakers.

Technology was basic by modern standards but fully functional for 2004 RV expectations.

FUEL ECONOMY & EFFICIENCY

As a towable RV, the 2004 Prowler 365BS has no onboard fuel consumption, but it does impact the fuel economy of the tow vehicle:

• Towing MPG typically drops by 25–40%, depending on terrain, speed, and towing vehicle.

• Proper weight distribution, tire inflation, and use of wind deflectors can improve efficiency.

• Larger water tanks (often 40+ gallons) add to weight and reduce towing efficiency when filled.

Efficient towing requires planning around load weight and wind drag due to the unit’s height and length.

• Used Market Value (2025): $7,000 – $13,000, depending on condition, slide function, roof seal integrity, and appliance status.
