Danny, I've got a '52 Suburban on an S-10 4x4 chassis. The swap should be about the same, maybe easier for a pickup. The US Body page is
HERE but is pretty brief and the pics are small. You'll need a long box S-10, you could easily shorten a X-cab, since they're easier to find optioned-out. My web page covers some of the things I ran across doing this swap.
The reason I chose the S-10 was because I wanted a 4x4 with IFS with tires that fit in the wheelwells. Hauling wasn't a priority for me. You've got to figure out what you want out of your truck when you're done and go from there. Make sure you keep your mind open about things and do your own research. I'm sure you'll find this with any swap, but there are a few people out there who have a little "posterior intrusion"

for the S-10 despite having no experience with anything other than a rusty stocker. It's not a bad chassis but I don't know if I'd use it to haul a lot of stuff without some beefing up.
And, by the way, I've also got a '84 S-10 4x4 Blazer with a 350/350 powertrain as my daily driver, so putting some muscle into them is do-able. I'd say the engine swap is even easier with the AD body swap. Drop me an email if you want.
