48" to 63" day cab    84" to 90" single    104" to 112" double there were also some 72" to 78" 3/4 sleepers used by big carriers to maximize cargo area within length limits. Length varied by brand and year.

I can go with that, those are good ranges.  It's going to vary by manufacturer. 

Freghtliner FLT, FLA, FLB COE sizes were...

Day cab - 48" (basically one customer, that hauled large empty tanks), 51", 63" (most Common, see AMT single drive kit)

COE sleeper cab - 75" (very small bunk, especially with options like breaking in well exhaust, for short BOC), 81" (rare), 86"( most common, see AMT dual drive kit), 96" double bunk (most common double bunk) sand 104"

COE's were the most common configuration when the size and weight laws applied to the overall length of the tractor and trailer combination.  Conventional became the combination of choice when the length laws were changed to apply to just the length of the trailer in 1982.

Interesting subject, I was about to ask almost the same question but mainly relating to Kenworth cabover's, I have found a video tour of the interior of a Kenworth Aerodyne which it says it is 90" I was wondering if it was a mistake as I have only heard of 86" & 110" sleeper cabs.

I know they made a shorter version Aerodyne cab for the Australian market as a right hand drive, I assume that it would have been 86" but the Kenworth in the video is left hand drive ???  Any info would be much appreciated.
