    I installed an aftermarket Class III hitch, nothing else.

    I'm considering a boat purchase but the trailering weight of boat, engine and trailer is going to be around 5300.

    Will be trailering less than 15 miles one way, no big hills, maybe twice a week.

    At the very least i assume I will need a tranny cooler but...do I need a bigger truck?

    Yes a trans cooler is the ticket
    I would just go to the scrap yard and get the cooler off another truck brackets hardware and lines / hoses

    The only difference between the 3500# rating of the Class II and the 5500# of the Class III is the tranny cooler?

    Still trying to figure this out but have realized I will need a smaller boat. If I put in a tranny cooler will the 3.55 rear allow me to tow up to 5000 lbs. with the aftermarket hitch?

    I will only be towing about 20 miles each time to the boat ramp and back.

    Your drivetrain can only handle 3500 lbs. With the 5000 lbs hitch, your drivetrain can still only handle 3500 lbs.
    With additional trans cooling, your drivetrain can still only handle 3500 lbs.

    If you were trying to tow 4000 lbs, I'd say that same thing publically, but (wink-wink) you'd be fine.
    But 5300 lbs, behind a 3500 lbs drivetrain?? Twice a week = regular use.
    Get more truck.
