The best brake upgrade is a full-size truck, Ranger brakes are adequate for a ranger with a small trailer but once you get past 1,500# your pretty much maxed out, even with trailer brakes, what if they fail for some reason? Ive had 1 full size truck myself, and while it was too thirsty on fuel to drive daily, nothing stopped a load better. 3/4 ton, creeper 1st / overdrive 5th 5-speed, 3.73’s 2wd but had the chassis weight to go through most snow pretty well . The extra weight of a full-size can be helpful when stopping, years ago I towed home a ‘72 cutlass on a tandem axle trailer, with a CJ-7. Had to (try) make a panic stop. No trailer brakes, slid all 4 tires on jeep more than halfway through the intersection, could of been bad, could of jackknifed. I do love the ranger chassis, but it has its limits.
