I forgot to mention before buying/installing a drive shaft disconnect, find somebody who will let you operate their vehicle to see how they like it. to re-engage it, you have to jam a fixed spline thingy into a rotating splined thingy which sort of sounds like using an osterizer to grind up ice.
and while driving with it engaged, be on the listen for a ping/ping/ping sound which you will hear shortly before it disengages on you.
I traded my S-10 in on my Dakota PU and later saw somebody driving it around town. I had an urge to ask him if he had ever been surprised with it jumping out of mesh. :)
