Then again, I'm one of those who refuse to tow with a 1/2-ton pickup, feeling that they're too light and short, and also because the mechanical bits underneath are generally on the tiny side. Including the brakes.
I'll buck that trend. I'm not towing 10k dump trailers, but I do routinely tow a 7k lb. trailer with my 1/2 ton RAM. It was factory configured with proportional trailer brake controller, heavier rear springs, a high-ratio (3.93?) posi rear, and pretty stout hitch receiver. It also wears 10-ply rated LT tires, not the usual P-rated crap that most have on their 1/2 ton trucks.
I'm not pretending it's a replacement for a 3/4 ton, especially on brakes, but I'm not relying on the truck to stop the trailer anyway. My trailer has brakes on
all axles (PA law), not just one axle like most factory trailers, and I maintain the brakes and wiring in good working order. I also
test and
adjust the gain on the trailer brakes every time I start a tow. For any one-time emergency stop, tire traction becomes the bigger limiting factor than brakes anyway, the 1500-series brakes will lock them up just as well as the HD brakes on the larger trucks for any one-time emergency stop.
Semi tractors pull trailers 3x their own weight at highway speeds, all day every day. I'm not one of these guys who believes he needs a truck heavier than his trailer, especially when I only do real heavy loads over local roads.
