But that the 9-ft bed was offered because most saw mills at the time only produced rough cut lumber to true dimensions. And 8 ft was a standard length. But it wasn't *exactly* 8 ft. It might vary a few inches (but never *less* than 8 ft). Thus, most of that standard 8-foot lumber would not fit in an 8-ft bed with the tailgate closed.I have no idea as to the veracity of this. But it *is* an interesting thought.
This has been a most interesting and educational thread! Forced me to research the GM Heritage site and review the 1948 Truck Manual. Sure enough the inside measurement on the bed is 108 1/4 " or 9 foot and 1/4 inch! Looks like those folks at GM wanted to make sure a work truck could do its work.
