M1078 and m1083 exterior bed dimension and height to bottom of bed?

As stated above does anyone have the actual exterior dimensions of the 1078 and 1083 beds? Olivedrab states the 1078 bed interior dimensions is 149" and the 1083 is 170". Doesnt make sense the 6x6 is roughly a 1.75' longer? Also anyone happen to have the height from the ground to underside of the utility bed?

Thanks in advance!
