Low range shifting up and down

[SGRACING]

Did some off roading this hunting season with the ZR2 and have noticed a very annoying thing with the shifting patterns.
The truck will stay in 1st gear until it tacks to 4500 rpms or so in low range only. Very annoying! Is this a normal operation for the ten speed in low range?

Sounds very similar to the 4low trans programming in our Jeep. It does have it's place, but is annoying most of the time.

What we do in the Jeep, is manual shift and run in 3rd gear or above when "trail riding" in 4lo. Crawling is done in the lower manual gears. The only time we use standard drive in 4low is faster runs in between obstacles.
