Description

Happijac 4820 (736515) RV Electric Truck Camper Loading Jack - Leg Only - 4 Pack
This is a replacement Happijac 4820 camper jack four pack. These jacks are compatible with Happijac's newest CCS Motors for the most modern camper stabilizing, loading, and unloading features. Made stronger with a dramatically increased load rating for increasingly popular double and triple slide truck campers. Equipped with zinc plating, a built-in wiper system, and higher tolerances making the new jacks quieter in operation and more resistant to corrosion.
  • Load, unload, and stabilize your truck bed camper
  • Square Tube: The design promotes a secure connection and a stable lift
  • Legs Only: Replacement legs for electric jacks
Square Tube Design
The square tube design allows for a better fit and alignment with the camper's mounting bracket. This can result in a more secure and stable connection between the camper and the jacks. This design also offers increased rigidity, which can help to prevent twisting and flexing during operation, resulting in a stable and secure lift.
Replacement Legs
These are replacement jack legs for the Happijac electric truck camper jacks. This means these jacks do not come with top caps and do not come with motors, these jacks are not considered an electric jack until you add your current motors to these jack legs. These are the primary load-bearing components of the jack system, and they are used to lift and support the weight of the camper.

    Panther good, Happijac/Lippert bad

    Posted by Unknown on Sep 5th 2025

    Panther RV has excellent customer service, but Happijac/Lippert is the opposite. They were nonresponsive on the case number they themselves opened regarding my old, binding Happijac camper jacks. One of the new Happijacs had the lower threaded hole off by 1/8" and not remotely square. As a mechanical engineer, that is inconceivable to me on a production part. I ended up having to modify my bracket to accommodate. $2000 later, I'm still having problems raising and lowering my camper. I wish I had gone with any other brand, even if it meant modifying or replacing all my brackets.
