There must be a way to do this with a.....2017 Silverado

I am trying to hook up my 4 flat boat trailer plug AND my wire from the camper 7 way to the truck. The truck has a plug for both but once you plug either one in, there is not enough room with the spring door to get the other one in. Is there some kind of work around here so I can use both going down the road? Thank you. Bob

P.S I have a pic but is there no way to post it without it already being on the web somewhere?
