Both the 7-pin Pollack RV connector, and the 6-pin connector commonly found on older stock trailers have their own ground wires.

I suspect that grounding wire might be an issue on the utility trailer. It works on the F150 because you're using a different shank and ball that isn't as rusty, and it can get a good ground through the hitch. It works intermittently on the F250 because the shank needs to rattle into just the right position in the truck's receiver to make contact around the rust.

The most likely place for the ground to be a problem is where the white wire attaches to the frame of the trailer.

you will have a lot less trouble if you run thet White wire to the NEG post on the battery.
