We bought our Styleside with DIY projects in mind. You said the Flareside's width at the tailgate is 46". A 4'x8' sheet of plywood or drywall wouldn't quick sit flat. We also never would have gotten our new couch and loveseat home in the Flareside (why pay delivery charge when you've got a truck?) You wouldn't think that extra 8" makes a difference, but you'd be amazed.
