That sounds like my trailer. everyone else uses it more than me. Since we moved I forgot to renew the registration... so it's been pulled all over creation and it isn't registered! OOPS!
Last guy who used it complained the lights weren't working, so I asked did you fix'em? Of course he says no!! SO I says .. if you weren't worried about that then I guess you didn't care that it wasn't registered!

Do you like the new trailer lights? Expensive?
