Anyone Install Shore power to rear bumper?

Has anyone installed their 30 amp shore power plug to their rear bumper? I was thinking about looking into installing my 30 amp shore power to the back of my bumper next to my hitch 7 way plug. Im thinking it may be a good way to stay stealth and keep from installing shore power inlet to body side. One thing that concerns me is being able to make it water tight. Pros and cons are welcome. Thanks
