It would have been easier to find the problem if it was the trailer wiring. That's the bad news.
Sounds like you've had this problem before or maybe your just an electric/wiring genius!
Regardless, I will check the fuses tomorrow. It's possible that one of them could be bad. Although it might be worse that the problem is the truck and not just the light, at least I have a concrete place to start my investigation. I know I've knocked the light receptacle off on some snow banks so I may have damaged one of the wires.
