For those that have done it how large of a wire size did you go to and how much effect did it have? I have a 2001 Suburban and know I have 12v to the center pin on the 7 pin but no idea beyond that of what I have.
Think not only about the vehicle side, but also Elkhart uses the cheapest wire they could between the trailer 7way and the batteries.
I'd recommend looking at a minimum of 4ga wire straight off the alternator, through an isolator or solenoid, all the way to the trailer batteries. Through a fuse in there somewhere too.
No I haven't done this but studied it in close detail. Instead of dealing with low voltage fickle DC, I ran an extension cord that allows me to run my small Yamaha generator in the truck bed and power the trailers charger directly.
