Tow mode on my Chevy does 2 tings: 1-it causes shifting UP at higher RPM. 2-if going down-hill, it holds the gear your in and will not let it shift up to the next higher gear. So, if your in "D" and you start to go too fast down-hill, hold the brake until you slow down, and down shift. Then let off the brake again and the "tow mode" will not let it upshift. It's doing the same thing as manually down-shifting without moving the shifter.
Otherwise, just keep the truck in '2' all the way down and apply brakes only when the speed increases too much to slow it down. You do not want to hold the brakes all the way down the mountain.
You'll not have any problems on the Interstate, but if you travel some of the back roads, I doubt you'll ever get out of 1st gear all the way down!
I guess he can remember this if he ever decides to trade his 2005 Dodge on a Chevy!
