you may have to rig up something on your own.. i riged up a "hot wire" between my truck and trailer batteries cause when the trailer generator is on it can charge the truck battery too... so i could run stereo in the truck and charge the battery etc....also charges the trailer batteries off the truck alternator while traveling...i just ran an extra wire with its own plug.

i used like a 12 gauge i think... i ran it off the positive of the battery.. im sure i should of used a bigger wire but i got it fused at both ends with 15 amp fuses and theyve never blew..and it works fine... i just got a generac plug from autozone and wired it up right by the trailer plug on the bumper
