If you are not using your Tow Haul when towing or hauling near or at your GVWR (hence the name), you are cooking your transmission. Get a Scan Gauge and start monitoring your trans fluid temps.
Even on seemingly slight grades the temp will creep up. Engage the TH and it will drop 10 - 15 degrees in just a couple of miles. On long, steep grades (6 - 8%), you can engage TH and cruise for miles to the bottom without touching the brakes all while not burning a drop of fuel. The difference in mileage will be negligible and your brakes will last far longer not to mention avoiding overheating.
I am wrapping up an 18 day trip through the southern Rockies and have used TH about 90% of the time with excellent results. Tow Haul is a wonderful thing but only if actually use it properly.
