Looking For A Replacement Distribution Box And Converter For My Jay Flight Trailer
Updated 10/30/2025 | Published 10/05/2025
Question:
I have a 2009 Jayco Jay Flight travel trailer. I want to upgrade the converter and distribution panel. Is this what I need? Or what would you suggest: Progressive Dynamics 4000 Series Mini RV Converter w/ Charge Wizard and AC/DC Distribution Panel - PD4045KA

Hey Bruce,
Without knowing what model your original unit was it is hard to say if the Progressive Dynamics # PD4045KA is a direct replacement. With that said since you are replacing the whole distribution panel this will work, you just may need to make modifications to the cutout. This unit requires a rear cutout of 10-3/4" long x 7-1/4" tall. I would say in most applications modifications are going to be made to the cutout since it is a different size. I would recommend this unit as a good 45 amp upgrade with the charge wizard.
Do You know what your original converter was?
