I'm gonna throw this out there. I don't know the layout of your Jayco but on my old Starcraft the batteries were on the front tongue and the converter was in the rear kitchen. 30' of 8 gauge wire between the 2 was causing a large amount of resistive voltage loss and my tongue batteries NEVER could get a full charge through no fault of the converter.
From the pictures it looks like your converter is probably under the fridge about 3/4 of the way back from the tongue - - so you could have a similar bad factory design as I had.
For me, moving the converter was the easiest solution so I could get some heavy gauge wire from the converter to the batteries. I put it in the front storage compartment and solved the problem.
Just throwing this out there as a converter MAY not solve the issue....
