I have a 28’ TT. Front bedroom and my main setup batteries charge controller and inverter/charger live underneath the bed. My question is my main fuse panel for the trailer is in the very rear , if I installed another charge controller near that panel and a few panels on the rear of the unoccupied rear of the trailer roof could I connect directly to the fuse panel or should I have a new run to the batteries in the front of the trailer?
