For those of you with custom bumpers who have 6 or 7 way trailer connectors, where do you have yours mounted? I have a 7 way plug and just welded the bracket to the underneath of my bumper. Problem is, now its the lowest point in the rear. I considered flush mounting it with the 2x4 main beam, but don't know if that is the route I want to take. I have to pull trailers with electric brakes at work, so a flat four way plug won't do me any good. Thanks
