LB,
I don't drive my trucks fully loaded so my habbits may be different than your's. I drive my 2-speed rear trucks as follows.
From a dead stop I start in 2nd gear with the rear in low range. I work my way up to 4th or 5th gear (direct). If I need more speed I pull the rear selector switch into Hi range, let off of the gas, let the rear shift and back on the gas.
As I approch a red light I start down shifting the trans leaving the rear in Hi range to help slow the truck down. If the light goes green before I come to a complete stop I get back on the gas. If I start to lug the engine I either shift to the next lower gear on the trans or if I'm already in 2nd gear I push the rear switch back to low range, let off the gas, wait for the rear to shift and get back on it working my way back to direct gear/low range and do it all over again. My engine is strong enough to overcome the split between the trans gears that I never need to "split-shift" using the rear, so I drive it like I have OD...2L, 3L, 4L, 5L and then 5H.
Hope this helped...
Mike B
