After one stop on stock size tires my brakes were cooked and useless.
And my truck is one of the lightest out there, being a factory nonAC, no cruise, manual everything, 2wd, stick shift
A fully loaded 4wd Durango will easily weigh 800-1000 lbs more than mine. And I'm tipping the scales at 3900 with a full tank of gas and a 220lb driver... Yet the much heavier truck will have the same brakes
