The shore cord I got with my trailer is a 30' cord. I swear it looks like the cords on the new trailers are 50'. Maybe they are a smaller diameter wire and they just look longer. I really wish they would have come with a 50' cord. I have been short a few times due to the shore cord hookup being on the very back of the trailer. I have a 30' 30amp extension cord that I use in these situations.

Just curious.
