I thought I would add one more way to attain 2wd low. I wanted nothing to do with switching to manual hubs, though now I wish I had done twin sticks because it's more elegant than what I did.
I found that there are two vacuum switches which activate/deactivate the front axle when you shift into/out of 4wd. This system is called Automatic Differential Disconnect (ADD). I found which of the switches locks the axle, and wired a switch inline with its power source. Now I can just flip the switch, disconnecting that vacuum switch, and making it so the front axle stays disconnected when I shift to 4wd, allowing 2wd low. Yes, the driveline is still turning with this option, but it's not like I'll be driving down the highway in low range, and I spent about $10 to get it done.
Like another mentioned, I use 2wd low for wrestling around heavy trailers with my little 2.7l tacoma.
