Also, I agree with Frank3 that the rears should not be working so hard. Definitely check the front calipers to see if they slide in and out freely. When a caliper sticks, the inner pad is worn much more than the outer pad because the piston pushes on the inside pad whether the caliper sticks or not.

So you're pulling a trailer equipped with electric brakes, but they are not being used and you're wondering why your truck's brakes are overheating? smh

Important to note that the rotors are designed to get pretty warm.. 4000# is about all I'd be comfortable pulling with the 1500.
Are they too hot to touch hot, or just very warm?

if the rear calipers were seized or dragging; you would be smelling burnt pad, and the rim would be to hot to touch.

Thanks for the advise.

Could be Sticky bracket where the pad sits in the clip on the Mounting bracket, sticky piston in the caliper, sticky slide pins on the caliper.
Clean up the bracket and reinstall the clip, check for free-floatyness of the pads. Checkout pad life.

I don't know what shape your rigs in. My 07 came from our Canadian brothers up North and was quite rusty from they day I got a screamin' deal on her.
If yours is anything like mine was it might be easiest to jump ahead and replace those cracked brake hoses and trade out for some re-manufactured calipers. Guy could even do all four if he wanted to get carried away...
