Replacing the lights on my new to me 2005 Triton TR20X trailer. After removing the lights I noticed some rusting on ground wire screws and moisture on the inside the trailer. I had fished earlier that morning. This is a tube type trailer. Anyone ever drill a drain hole in the lowest portion of the trailer under center running lights? I thought this might aide water exit from inside tubes. Never had a tube trailer always c-channel. Thanks for your input.
