Tow haul switch???
So now that I have a 2003 gmc k2500HD extended cab long box to tow our fifth wheel, am wondering how to use tow haul switch, do I activate the whole time towing fifth wheel?

When in "tow" mode, the torque converter remains locked so transmission runs cooler. Shift points also change to a bit higher RPM. Use anytime pulling trailer.
You don't say engine/transmission combo. If you happen to have the Allison transmission you can tow in overdrive. Randu
