NOt sure about what you got, but we haslte with our share of worn out dry/reefer trailers. We have seen our share of shorted out marker light wiring at the top of the trailer near where the doors close. Slamming a door shut will often make the beaker in our dash pop and we have to reset it.

No on pigtail, put a new end on it also. Can swap one out in the morning. If one bulb on an led light cause a short like this? Saw I had another one with a bulb out. Never had an issue with this with my previous truck pre June and while I was waiting to remove mandate I had it on another older truck and no issues in a week in August. I thought maybe bouncing down the road did it but this last fuse blew while I was parked and getting loaded. Could a relay be doing this? This is a 30 amp mini fuse that's blowing. I'm thinking it's in the truck.
