Looking for suggestions or a kit to create a pass through for a door for my generator cord. I purchased a generator this year for my travel trailer and in hind sight i purchased one with a 30 amp rv plug and not the 30 amp twist lock plug. I see all sorts of pass throughs for the twist lock but for me to take advantage of that i would need extra adapters and that gets a little expensive and just creates more room for issues not to mention over the past several years we have not had a power failure. All i would be powering up is my pellet stove and TV so its not going to see a lot of load so i was thinking of just a 15/20 amp extension cord for the pass though.. So far all i have come up with is getting 2 30/50 amp outdoor outlet covers and drilling through the door and having one on both sides and just stuff it with some insulation when not in use.. Then i can just use my heavy duty extension cord and pass it though easily. My doors are to tight to use a lay flat cord under the door so that is not a option.
