I have a supercab and I am happy that I have the 6.5' bed to go with it, I can lay 4'x8' sheets flat with the tailgate down. Combined with a backrack/hitch extender I can get 16' long lumber.

The backseat is passable with my dog and kids, but barely. If they were able to take some room from the front where there is no engine and give me both a reasonable bed and a crew cab I would be happy.

A lockable frunk is pretty attractive though so that you don't have to worry about leaving tools in the bed.
