Whether or not round or 'blade' it will be a male plug.......trailer cord plugs into receptacle on tow vehicle.
4 wire will only give you right/left turns signals, a ground & maker/taillights
7 wire will provide power for charging trailer battery, power to activate trailer brakes via brake controller and back-up lights in addition to 4 way wiring.
You will at least need to run wiring for brake controller so trailer brakes work when tow vehicle brakes are activated.
Wiring/function of trailer plugs etc.......LINK
Think you will be very close on MAX weight.
Does your minivan have a tranny cooler, a weight distribution hitch and hows your radiator
