properly is a "loaded" question...no pun intended. There will be a lot of different opinions on how to use it. Depends on a lot of factors. An auxiliary trans is really for a "loaded" tuck. It gives you a lower set of gears for starting, hills, and moving around slowly. For you it is probably just bragging rights and a cool accoutrement for the truck. I would just leave it in direct for most driving and you might use the OD in forth if your on flat ground or going down hill, and IF you want to go that fast.
