Cross Member Drop?

I 'm eager to see how the drive shafts turn out & work myself. A buddy of mine wants to build a tandem axle pickup & we've thought of a bunch of ways to make it work. A divorced NP203 would be a better chose for doing a tandem axle if you were planning to have both axle drive the truck. I say this because the NP203 t-cases were a full time t-case with a differential in them allowing the front & rear dive shafts to turn at different speeds, like when turning, but the front & rear drive lines could also be locked together in 4wd & 4-LO. The down side of the NP203 is they are a chain driven t-case, are about twice the size of the NP205 & weigh about twice as much too. With a Np205 I'd drive it with the t-case in 2wd & shift into 4wd when the extra traction is needed, adding ARB air lockers to the two rear axles would give you the ability to turn all four tires at once no mater what and the ultimate traction.
