After having my lab puppy chew thru my trailer wiring at the trailer tongue, I have thought about making a pigtail to hook up between the trailer and my truck. Basically, shorten the harness on the trailer to where the connector is inside the tongue and use the pigtail to hook up there and run it out to the truck. That way I have no wires hanging when the boat is parked at the house and the dog can't chew thru them. Would there be any reason this wouldn't work? I can't think of a reason why it wouldn't.

Pigtail would go between the connectors in the pic...
