drove an astro 95 several years ago. most uncomfortable thing i think i've ever been in. couldn't get the seat back far enough to stretch out because of the bunk. plenty short on creature comforts. it was a work truck only and not much else. gmc 9500 short nose conventionals were more easy on the back. an option on the 9500 long nose conventional was the 12 v 71. 3 to 4 mpg, but would pull a house off the foundation. 6-71 jimmies had a sound of their own. i miss that, along with the smell of the old diesels. my favorites? old "bubble nose" or "cannonball" jimmies and the old crackerbox jimmies.
if you like big old trucks, be sure to check out spanky hardy's stable while you are here.
