> At least in the 2000s a 4x8 sheet of plywood will not fit in a compact pickup but lays flat in a fullsize.
I hate to break it to you but the F150 XLT Crew Cab tops out at 6.5ft. Your 4x8 plywood won't fit with the gate up. And if you have to put the gate down for standard sizes do you really need a fullsize pickup to do it?
If I'm only hauling a few sheets than I leave the tailgate gate up and lean the board on it. Straps can't hold just a few sheets very well laying flat unless the attachment points are significantly lower. I learned this the hard way when I had to pick up a couple sheets of plywood off the highway. The other option is to lay a few 2x4s under it to raise the sheets and give the straps a better capability to hold.
Yes because in a smaller truck (like a Tacoma) the plywood doesn't fit between the wheel wells so it has to be loaded awkwardly and reduces what else you can haul because you can't put things on top of the plywood.
