2007 Holiday Rambler Neptune 36PDQ

The 2007 Holiday Rambler Neptune 36PDQ is a well-balanced diesel pusher that offers the space, ride quality, and durability buyers look for when stepping into a true Class A diesel coach. Built by Holiday Rambler, the Neptune line was designed to deliver diesel performance with a comfortable, residential layout.

This coach is powered by a Cummins turbo diesel engine paired with an Allison automatic transmission, giving you the reliability, torque, and drivability that diesel pushers are known for—whether you’re cruising the highway or working through elevation. With just 44,298 miles, this is a lower-mile example that hasn’t been overused.

At just under 37 feet with four slide-outs, the 36PDQ opens up into a wide, livable floorplan that feels much larger inside than it does behind the wheel. The quad slide design creates a true living space with opposing slides in the main area, making it ideal for extended trips or longer stays.

Inside, you’ll find a comfortable living area with sofa seating, dinette, and a full entertainment setup, along with a well-equipped kitchen featuring solid-surface countertops, refrigerator, cooktop, and convection microwave.

The rear bedroom offers a walk-around bed, wardrobe storage, and washer/dryer prep, while the split bathroom layout provides a larger shower and better functionality.

Additional features include:

Onan diesel generator
Dual roof A/C units and furnace heat
Hydraulic leveling system
Full basement storage with pass-through compartments
Power awning

This is a great example of a diesel pusher that gives you the ride, capability, and space of a larger coach without stepping into a 40+ foot platform.

If you’ve been looking for a clean, lower-mile diesel coach with a proven drivetrain and a highly functional quad slide floorplan, the Neptune 36PDQ is a strong option.
