hmknightnc, Thank you very much for the info. What is your suggestion as to where and how I would mount the receptacle to the trailer? You mentioned a convenient place but I'm clueless as to where. The bumper, drill through the trailer skin, etc.??, I'm baffled at my own ignorance. Also what gauge wire would you suggest that I use since it will be at least 29' to the battery? Before I became a senior citizen many years ago, I think that I could have figured it out. I'm embarrassed. Have a good evening and thank you.
