On cherolet.com they list their two bed sizes as Large and Large. One has 70 cubic feet and one has 56 cubic feet. Where is the short bed option? Is it the 56 cubic foot option? Maybe someone can elaborate on the short box option being deleted?
I would imagine the larger one is the "standard" 8 foot bed and the smaller size is your standard 6.5' bed.
You can get a 5' bed a 6' bed or an 8' The 5'er is on 1500 trucks only. 2500 and up you can get 6' or 8' but not the 5'er That is what I remember and my memory sometimes tricks me so I could be off a bit but I should be preety close to what GM offers...
