Will Newer HappiJac Truck Camper Kit Fit Older 4800 Model Brackets and Wiring  

Updated 02/04/2026 | Published 07/02/2024

Question:

Will the replacement jacks for the 4800 series 36.5 inch lift bolt to the existing 4800 brackets on my camper — or do I have to replace the brackets as well? Same question about the wiring and control board — can I use my existing?

Hey Robert, thanks for reaching out!

Yes, you should be able to use the existing brackets and wiring from your older 4800 series HappiJac system to install the HappiJac Electric Truck Camper Jack System # LC736515-ELKIT.

Hey Robert, how did things go using your existing brackets and wiring with the new HappiJac jack system? Knowing how the fit worked could really help others upgrading from an older 4800 setup.

@JesseM I was able to use existing brackets, wiring harness, etc and it worked fine.
