Ah okay. I did not think about that... Idk how it is wired really but the mid-bed trailer connector looks like it is wired with like 16AWG from what I saw when I popped it out. This is super good info that the trailer wiring the truck has is for trailers not RVs I never would have known. Thanks man I will need to figure that out as I fix this to make sure they work together wellIt's more than heavy enough for all the lighting. It will easily handle up to 15 amps... The only thing different you might want to run is 10AWG or even 8AWG from the isolator to the charge wire for the camper battery/ies. Especially if you are going to be using the truck as the main source for charging the camper battery/ies.
