Are big window cabs rare compared to small window cabs???

[GMCNUT]

Seems that big window trucks tend to have more factory options on them - they will twice as often have the Custom Cab trim and bright metal vs white steel grille and bumpers, factory Automatic or A/C, tinted glass etc....very few only came with a single cool option like the BBW, so when you stumble onto a big window sticking out of a barn or in a salvage yard, you already know before you walk up to it that its probably going to have other options on it, which lends to desirability too. I have two BBW trucks and one small window and love all old trucks.
