The back wall in the front storage is only about 3/8" thick. The back side, which is located on the drivers side of the pass thru is where you wold want to check for any wires. This wall is not a stud constructed wall just the plywood. One issue with the "true" battery disconnect is to make sure that it is on while traveling. The on board battery does power the emergency brake system in case the RV becomes detached from the tow vehicle, this required by law for any trailer with brakes and over a certain weight.
