ok, now how does this compare to a 4.1 or 6.1 tcase?
Aside from the extra gears you get, Which would be better for stock gearing, (axle) and say 33-34" tires on the street?
What about the trail?
Got a rough idea for cost for dual cases?
Am I asking enough questions? 
We have a 4.24:1 in one of the cases, the sidekick case.
This is great for the slow, crawly stuff.
We have stock Sammy gears, ~2.2:1 in the Sammy case, for regular like 4wd low. (like most of the rest of the planet)
But combine them together (4wd low + 4wd low) and put the tranny in 1st gear and it will climb nearly anything at idle. (overall crawl ratio is ~180:1, when stock sidekick is ~34:1)
Overall I'd say that by just doing the dual t-cases in a sidekick (Sammy +Kick cases) you wouldn't need diff gears and would be easily able to handle 33s on the street without issue. (the Sammy has a reduction in high)
OTT Kicker 3 = ~$600 US. (Send them a Sidekick t-case to modify)
Sammy T-case = ~$150 US. (Average price from a junkyard)
Added together it's cheaper then a set of 4.24:1 gears alone.
But you may have to add the costs for custom drive lines, custom cross members, custom body work, etc. (Which you can do yourself) to accomodate the additional t-case, shifter and moved output shafts.
