Updating a mid-90's ex-military veh (24 volt system).

What problems will I encounter updating a mid-to late 90's GMC 3/4 ton trk, ex-military vehicle for street and mild trail use?  It is a 6.8 Diesel, automatic trans. and a 24 volt electrical system. Obviously  I'll fix what is broken or worn out but am I opening a can of worms?  Thanks.  

Sounds like a CUCV II.  You can see the spec. sheet below.  There really isn't much that's too different from a K3500 of the same year.  They were commercial/fleet trucks that were repurposed for the military.  If it's fresh from the military motor pool, I'd suspect that it's in good running condition.  Should be 5/4T and have a 6.5L diesel though.

 

Thanks for the reply, sorry I didn't get back to you sooner.  The spec sheet is very helpful.  What bothers me is the 24 volt electrical system.  How much of a problem will that be replacing components, repairing wiring glitches, etc.? I've found a source for shop manuals so that will help.  But before I dive into this thing I want all of my bases covered.  Again thanks for the info.
