I was in the same boat as you a while back which is why I decided to get my k3500... you (like most people) seem to think GM IFS is an absolute down-fall to the '88+ trucks but after daily driving one for over a year now let me tell you it's nice.
I wouldn't want to take it out and wheel it but at the same time for pavement pounding day after day it's a nice comfy ride. I've had my k3500 out in the dunes a few times and I've never had issues with the 4wd so for a DD/light off-road rig the GM IFS is a great option.
I hear ya' on wanting to stick with the '73-'87 trucks... I kind of miss daily driving my k10 in that aspect BUT you can pick up '88-'98 chevy's for pretty cheap these days and you have great fuel injection, good tranny's and a plush ride not to mention heat/defroster/AC that actually works...
In your case maybe you should look into a '88-'98 tahoe... smaller than a burb but still enough space to haul people/dogs around and I'm sure you'll get the same if not better mileage than most '73-87 rigs (except the light 2wd diesel rigs
)...

I'm also perfectly aware of all the odd habits of older vehicles. I can't lock my rear hatch or it'll stick, the cruise control does and doesn't work, water leaks in on the passenger side from somewhere on the firewall, blah blah blah...
