Here are the pictures from the work prior to the trip. I got the aux battery and charging system in, as well as installed an inverter for charging up the cameras and laptops.
drilled holes for the rivnuts and through bolts
basic charging circuit
A closeup of the crimps. I used a vice and a $17 hammer type lug crimper. I am happy with the result.
clearance on the fridge
pretty much a mess. This was an all-nighter 2 days before the trip.
