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?
Forum Discussion
- I also use mine any time that I am towing.
- I leave mine activated any time I'm towing or hauling a heavy load - that's what it's there for.
