Replaced a Marinco 50A receptacle that was installed improperly by Camping World (they used rivets instead of screwing it in through the wall and in to backing). I like this unit because it has a light and the prongs do not succumb to heat the way others do. It is also provides a better fit and doesn't leak during heavy rain. I have had this connector on other travel trailers and never had issues. I added a double gang waterproof plate for added reinforcement and waterproofing.
