I know the battery
wiring on mine uses 12AWG to the converter. I purchased some 10AWG last week and planned to install that for a bit better capacity between the tongue and converter. I was having a problem running a 12 volt CPAP machine and initially thought it was the weak 12AWG wiring causing too much voltage drop, but after checking the connections behind the converter, I discovered Scamp
ran several ground wires off the main 12V negative wire by using those ScothLok type connectors (which I dislike) and I think the ScothLok type connectors actually cut into some of the 12AWG wiring, thus diminishing it's capacity. I disconnected all the ScothLok type connectors and ran the wires to a grounding block I purchased instead, and my CPAP runs fine now even before I've run the 10AWG, so maybe the 12AWG is fine after all.
