I checked something today on my 4wd Gem2 Tacoma. I'm 5'9" tall and pretty much average build. I can stand flat footed on a concrete floor reach over the bed sidewall and easily touch the floor of the bed.
Now, my full size 05' GMC 2500HD, 2wd.....I could not touch the bed floor reaching over the bed sidewall. But that was a FULL size pickup.
I figure JayQQ97 must be about 5'0" or less with possibly freakishly short arms.
