I used Anderson SB-350 connector between the TV and the Trailer. In the TV is a Blue Sea
ACR and an Odyssey PC-2150. In/On the trailer is 200W solar, Blue Sky MPPT controller, and an Odyssey PC-2250. When plugged together the ACR would connect or dis-connect as voltage dictated. If I started the TV and drove off the ACR would pull in. As the sun came up when parked, the ACR would pull in. Both batts charging.
