I have a F-250 Crew Cab, and wanted a quality power outlet for a Diesel Fuel Transfer Pump, Lights, etc. in the bed of the truck. In the truck cab I have Six Overhead Switches ( four 25 amp & two 40 amp) to power the outlets. The Marinco kits fit my requirement for a neat and reliable connection.
This plug setup works great..I use for my weed sprayer that I hook up to my Kubota rtv to power the valves while I spray I can shut it on and off with a toggle switch
