Question:
I’m looking at putting the solar panel kit on a gooseneck trailer to maintain battery for auxiliary winch and I’m wondering if there’s an extension cable kit to be able to reach?

Hey Jordan, what you'd want is an extension SAE solar panel cable which we don't have a perfect solution for at this time. We have the part # e84RV which is an SAE connector on one end and then 48 inches of wire on the other but you'd need to attach an SAE connector to the other side. Or the other option is to just cut and splice wire into the harness that comes with the solar kit part # MA79JR to add the length you need.
