my old man calls 8ft beds shortbeds, the longbeds are the 11 footers.
I agree with tanner, the 11 ft long chassis cab is quite the setup.
I am trying to find dad a GMT800 Ext. cab 11ft flatbed, as they do exist. I wish they offered the ext. cab on the GMT400s, even as an 8ft straight rail chassis cab, let alone the 11ft chassis cab.
back on topic..

as far as having 4 full size doors for family use, why not get a burb again? 4 big doors, and a short wheelbase.
dad had a friend that has since passed on, and he ran a huge salvage yard (1,500+ 2 cyl. JDs, plus another many thousand of other brands, his estate auction took 8 days to sell) and dad asked him what is the perfect truck? his response was, you can have 10 trucks and none be the perfect one.
So, the solution is multiples.

at least that is my theory.
