jenRAK©

jenRAK© is the first and only integrated onboard generator system designed exclusively for your Airstream travel trailer. Fueled by clean burning propane and built around the most advanced inverter technology from CUMMINS/ONAN.

Designed to be minimally invasive and easily removable as it utilizes the existing spare tire carrier mounting points and only requires the drilling of two 9/16″ holes through the forward a-frame cross channel (located directly behind the battery box).

The kit has been engineered to reinforce the frame crossmembers it mounts to. The carrier is laser cut from 3 pieces of 3/16” HRPO steel and incorporates alignment features similar to those of LEGO blocks. Once formed, the parts are snapped into place then welded together at these features to create a reinforced structure which is able to protect the generator and belly pan/holding tanks from road debris. The front area is formed to cradle the forward chassis cross member it mounts to — this interface helps in distributing load across the beam and strengthening the frame in that area in a symbiotic manner. Once installed, jenRAK© forms a structural tie between the fore and aft cross channels and distributes the weight of the assembly out toward the main frame rails. A positive net effect of this is dramatically reduced subfloor flex and bounce inside of the coach – our system actually makes the subfloor more solid by reducing flex and bounce.

IMPORTANT:

THIS SYSTEM IS DESIGNED FOR INSTALLATION ON CONTEMPORARY AIRSTREAM TRAVEL TRAILERS 23 FEET AND LONGER. DO NOT ATTEMPT TO INSTALL THIS SYSTEM ON A 16, 19, 20, OR 22 FOOT MODEL – THE FRAME STRUCTURE, RIDE CHARACTERISTICS, AND GROUND CLEARANCE OF THESE MODELS WILL NOT SUPPORT THE REQUIREMENTS OF THIS SYSTEM.

INSTALLATION REQUIREMENTS:

THIS MOUNTING SYSTEM REDUCES GROUND CLEARANCE ON THE FRONT OF THE COACH BY APPROXIMATELY 1 – 2 INCHES DEPENDING ON VARIATIONS BETWEEN INDIVIDUAL COACH MODELS.

A LIFT KIT IS REQUIRED TO OBTAIN ADEQUATE GROUND CLEARANCE.
