I couldn't agree more, they're junk in any weathered situation. The do make them packed with dielectric grease but I'm pretty sure they're for home wiring splicing. Never seen these type of nuts for small wiring. I guess you could 'make your own' easy enough. I've fallen in love with the heat shrink butt end connectors you can get all Walmart. The splice is completely sealed once your done.
Thanks for your response.
My apologies, I should've told you I replaced all the lights on the whole camper when I bought it last year with LED markers. When I did that all of the wire nuts got tossed and I made sure my splices were weather proof.
I think you might have hit the nail on the head with that front marker light on the door side of the camper having a short. The back of the new LED base plates are very low profile and the wires basically get squished behind it when I mount the light base to the camper. Very possible I hit the edge of the (+) wire with one of the screws when I was putting in on and pentrated the wire shielding causing it to ground. I'll have to pull that one off again and take a closer look.
Also, when I was doing the testing on the trailer pigtail's plug I had removed it and was using the raw wire end to eliminate the 'bad plug' possibility. When I put it all back together I did install a brand new plug for a little piece of mind.
Ultimately it'd be extremely helpful to have a wiring diagram of the external travel lighting in case the problem persisists but haven't come across anything. I guess I'll just wait and see what happens.
