Happijac 4220 (736514) RV Electric Truck Camper Loading Jack - Leg Only

This is a single Happijac 4220 camper jack. This jack is 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 jack quieter in operation and more resistant to corrosion.

Square Tube: The design promotes a secure connection and a stable lift
Single Leg Only: Replacement leg for an electric jack

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 jack. This design also offers increased rigidity, which can help to prevent twisting and flexing during operation, resulting in a stable and secure lift.

Replacement Leg

This is a replacement jack leg for the Happijac electric truck camper jacks. This means this jack does not come with a top cap kit and it does not come with a motor, this jack is not considered an electric jack until you add your current motor to this jack leg.

camper jack

Posted by henry rambosek on Sep 6th 2026

jack was to replace 4150 style but had to drill a new post hole as the old one had two post plus the bolt on the bottom. Bottom bolt doesn't line up with new jack.

I appreciate that Lippert offers replacement parts for legacy jacks including legs and motor drives. Panther is very responsive for well protected packaging, good pricing and quick delivery. My 1999 Bigfoot 2500 continues to five me more years of adventure.
