He is only 500 pounds over the "bumper ball" towing limit for non towing package trucks. The difference falls well within the PAYLOAD allowance for his truck. As long as he isnt retarded regarding driving up inclines, there is absolutely no need for EITHER cooler. A brake controller is worthless, his trailer has no brakes, and it is a really moronic move to put electric brakes on a boat trailer. If he wants to install brakes, he needs hydraulic disk brakes, which have no need for brake controller.
No, I'm not. I attempted to provide sound, reliable, advice. Nearly everyone recommends extra cooling when towing that amount of weight. I've had a transmission (on another vehicle) fry from heat while towing even less (though not much less) and have seen the engine temp climb many times while towing, so I certainly recommend extra cooling.
As for the brake controller, he mentioned that (without asking which), so I assume he knows what is needed for his particular trailer. Many boat trailers have electric brakes, including my own. Finally, most state regulations require brakes to be fitted on boat trailers over 3,000 pounds. His boat & trailer exceeds that.
