2007 Holiday Rambler Neptune 37PBD – 37’6” – Cummins Diesel – 7,000 lb Towing

This 2007 Holiday Rambler Neptune 37PBD is a premium diesel pusher built on the Roadmaster RR4R chassis with the proven Cummins 5.9L ISB (325HP) and Allison 6-speed transmission. At just 37’6” long, it’s easy to maneuver while still offering a full residential layout with two slide-outs, solid cabinetry, and plenty of storage.

What sets this coach apart is its towing capability.
Equipped with a 7,000 lb hitch rating, this Neptune is ideal for pulling a full-size vehicle, enclosed trailer, toys, or anything a serious traveler needs. The torque from the Cummins and the gearing of the Allison make it extremely comfortable to tow with — even in the mountains.
