This would be the most easily fabricated. Length is 93.3% overall body height if memory serves me.
Which would work out at 123.15" for Moby. Kinda long! I'll verify that.
If you could figure out how to collapse it, it would be an option to the trailer.
Ahmed body


So the "Stemco-TrailerTails" are truncated variations of this then...sort of
..with some limitation(DOT or can't make it longer than 1/2 the width), keeping them 4 foot long.
