. . . The danger of this is when your truck has a drive-line parking brake with the drum just behind the transmission. When the vacuum bleeds down and the rear end drops out of high and before it engages low, you are not in any gear. Thus, the truck could roll if on an incline. That is why you will read and hear about leaving it parked in the low range. . . .

Unless you engage the drive-line (propeller shaft)
"parking brake" when you park the truck?
