I carry the 50 to 30amp converter (dogbone) for another reason also. Sometimes but not always you can get a higher voltage reading from the 50amp circuit than the 30amp. I've always assumed that this was do to many more using the 30amp than the 50amp connection and that the 50amp was from a different feed than the 30amp. This is most noticeable when the campgrounds are full and there are a lot of air conditioners running. It works for me. Happy camping.
