extended cab/reg bed is 230.2 inches
CrewCab/Short bed is 230 inches

if you are talking about the 1500's that is

 

I don't know about the NNBS trucks, but my Z71 is about 6-8" shorter than my friends CCSB 1500HD. Basically it's just the extra width of the full door vs. the clamshell ext. cab door.

 

ECSB = 220.3
ECStdB = 229.9
ECStdB = 230.3 (HD)
ECLB = 248.8
ECLB = 249.2 (HD)

CCSB = 229.9
CCStdB = 239.9 (HD)
CCLB = 258.7 (HD)

The Ex Cab Standard Bed and the Crew Cab Short Bed are the same length.
