The power cord in the bumper compartment goes to the 30a Breaker in the bathroom.
From there the main wire runs back around the bathroom to the curb side where it goes into the wall and up to the ceiling and runs forward to the front breaker box.
The power is then supplied to the 2 circuit breakers, 1 powers all the outlets and the Univolt. The other breaker powers the outside outlet and the bathroom outlet in the overhead medicine cabinet . If factory equipped with a/c it would also be powered by that line.
In my project I ran a 3rd breaker from the front box and ran a line to the a/c I installed.
Take look at your other thread for what I did about the water damage .
