Reshuffled a 12 Volt power outlet that was tied into the water pump switch. Not sure what the thinking was to have it only powered up when the demand water pump has power.
Rewired it so that it has power all the time and added a new 12 Volt branch circuit with a master switch. Items like TV antenna power and some USB outlets will be connected to this new circuit. Master switch will allow for easy on/off en masse.
More planning and preparation for Grey Water tank. Originally I had planned to mount it on or below rear bumper of the trailer but after a few sample fittings I think I found a place underneath, forward of the fresh water tank.
