A buddy of mine had to use it to take off in his truck..he got his thoughts backwards and instead of building a firewood hauler with low gears, he built it with absurdly high gears..higher than 2.73's, and ran it with 35" tires..on mildly steep hills unloaded, you had to shift the np203 into low, take off in granny low, crawl into second, and when you topped out third, slip the trans into neutral, transfercase into neutral, double clutch, transfer case into high, transmission into second, and go back through the pattern...royal pain that resulted in the truck getting repo'd by a personal loan company.
