I have a '15 4Runner and a VRV flyer trailer. Each have their own battery, trailer trickle charges through the 7pin connection on the truck. I have a Ctek 250s and a standard MPPT Solar controller. One is for the truck the other is for the trailer. I'm not sure which would be better suited in which vehicle. The MPPT will just take solar and send Voltage to a battery, the Ctek obviously does similar. Am I better off with the Ctek in the Trailer taking the 7pin power input and solar and sending the second battery to the trailer or vice versa.
