3.83 first gear, 4.7 dual & 4.88 gears=200:1 crawl ratio
I use everything but 200:1 only gets seen in bigger/slow rock situations...was perfect at crushers in TSF. Factory high range w/ dual in 4.7 is perfect for trails plus it's easy to kick into 2wd for better turning.
that's what I'm saying, the lowest I have wheeled around in was something like 160:1, and even in 3rd (the get it gear) when you floored it you got up to a whole what??????? 5mph. Low gear's are dumb, 100:1 is fine.
