Well, I already posted this on this page here: http://www.imcdb.org/vehicle_61080-GMC-Astro-95-1973.html, but I figured
I'd get more responses if I posted it here. Anyways, if anyone can give me some more info on the GMC Astro/Chevy Titan tractor trailer, I'd be very grateful. By info, I mean: length/width/whatever, weight, engine specs, history, etc... All I know is that they were introduced in 1968, replacing the GMC F-Model "Crackerbox"/whatever Chevy's version was, & had an all-aluminum tilt-cab, a 10-speed tranny, & possibly an 8V71 Detroit Diesel. Also, I know that they were redesigned in 1980 & production ended in 1988. But that's just about all I know. If anyone has more info, please help!

On another note, does anyone know if Chevy had an equivalent to the GMC F-series "Crackerbox"?

As far as I know, Chevrolet had no counter part for the F-Series, however you may find this interesting http://www.6066gmcguy.org/Fmodel.htm

Oh, I've been there before. It's strange that they've been used as missile transporters.

Having said that, some sources suggest that the Crackerbox has an aluminum cab. I thought the Astro was the first to have an aluminum cab! Does the Crackerbox really have an aluminum cab.

Also, if the Crackerbox has no Chevy doppelganger, then it's a "Denali". Denali is a slang term I invented for GMC trucks without Chevy counterparts, named after the Yukon Denali (which has no Chevy equivalent, as far as I can tell). You could use the term for a Chevy vehicle without a GMC counterpart, but people might get confused, so I'd suggest the term "Avalanche" (after the Chevy Avalanche).

Also, as I've said before, please post any info you may have on the GMC Astro/Chevy Titan. I also have a theory about one aspect of that truck. I've also seen them talking about 70/80/90 series when referring to the Titan (or 75/85/95 in the Astro's case). My best guess for this is as follows:

70/75 series: Single rear axle, no sleeper cab

80/85 series: Dual rear axles, no sleeper cab

90/95 series: Dual rear axles + sleeper cab.

Am I correct on that?
