My new ordered MH will be coming with the screw in external connector on the side of the MH with probably a 25 foot 30 amp cord . My current MH uses the older style where I disconnect the shoreline power cord from the generator in a small compartment. I have a 25 foot extension 30amp cord that I attach to a 30amp exterior power box on the side of my house. I don't want to be using the new power cord exposing it to the elements day in and day out. So I see I can buy a pigtail that will screw into the twist-on connection on the side of the MH. Then connect my current power cord to the male end of the pigtail. However, the pigtail is 18" long and the connection of the pigtail and old power cord will be uncover and exposed to rain. Any suggestions as to how to prevent water intrusion and possible shock?
