Shifting from low to high range when towing

Shifting from low to high range when towing
So I'll be towing about 6500 lbs. The manual says that when starting from a stopped position and towing more than 4409lbs., I should start in low range and change to high range once moving (page 121). But to change from low to high range it appears I need to be in neutral (page 136). What am I missing here? I need to put the trans into neutral while I'm in motion in order to change from low to high range and then back into drive, all while in motion? Doesnt seem to make sense....??

Rjwil:
Here is what we wrote earlier .... the bottom line is you are entirely correct in your opening statement. I have practiced the maneuver and it is very quick and effective, once you learn and practice the steps, a bit. It does seem to provide a more controllable, easier start for the geartrain.
Just make sure you are coasting when you perform the shift, so when you are in neutral the rpms do spin up. Also, you do NOT need to pull the trigger to shift into Neutral -- good know. I ADDED BOTH BELOW.
Also, I find myself using LO range for backing up now, even with small loads, as the lower gearing makes the load move more slowly, so directional control is easier.

"NOTICE: Do not change from high range to low range while the vehicle is in motion. Doing so can result in damage to the transmission."
The procedure to change from Hi to LO or from LO to HI both require the change to occur while in Neutral (N).
Per the manual, "The procedure can also be used for changing from low range to high range" . . . (but NOT in the Opposite direction!) ... "with the vehicle traveling at a speed of less than 37 mph (60 Km/hr)"
So, when we are towing greater than 2000 kg (4409 lbs), we will need to start from a dead stop in LO, then accelerate to above 20 mph (32 km/hr), and before reaching 37 mph (60 km/hr), we will need to COAST THE VEHICLE WITH FOOT OFF THE ACCELERATOR, place the transmission in neutral (N) -- you do NOT need to use the trigger to shift in Neutral, change to HI range, then go back into drive (D) (must use the trigger). THEN PRESS THE ACCELERATOR.
For me, this means , I will drive in LO at below 35 miles per hour until I reach the interstate. Then, I will reach flat ground, move the transmission to N and change to HI range, then shift back into D.
