Description

Happijac 4820 (736515) RV Manual Truck Camper Loading Jacks - 4 Pack
This is a four pack of Happijac's 4820 manually operated camper jacks. A part of their 2019 line of products, these jacks can be upgraded 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
  • Manual Operation: Raise and lower the jacks with a crank handle
  • Legs Only: Replacement legs for manual 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.
Manual Operation
Manual crank jacks are simple and straightforward to use, with no need for an electrical power source or control system. Because manual crank jacks do not rely on an electric motor, there is no risk of electrical failure or malfunction. Manual jacks are lighter and more compact than electric jacks, making them easier to install and store. Manual camper jacks are raised and lowered with a crank handle which inserts in the receptacle located at the top of each jack.

    These 4820 jacks lift my Bigfoot 2500 truck camper with ease.

    The jacks seem to work well with my slide-in truck camper. There was a bit of confusion on my part when I mounted them to my camper brackets using all three jack bolts to the 3 holes in my camper brackets. This put the jacks in a position much too low. I had to use only the lowest bolt and put the included bolt in the empty jack bolt hole.

    Great product - quality construction - replaced existing jacks that had worn out - took less than 15 minutes each to install

    Quality made product

    The Happi Jac camper support legs were to replace an original set of earlier series screw jacks. They bolted right into original 1998 vintage brackets, original motors transferred over to new jacks, original wiring harness in tact. Consistently well made camper jacks, with steady improvements to design.
