Doesn't look like it in the photo.
Probably need to have the tailgate down, and might still overhang somewhat.
I agree. I’m thinking they are being careful with their words. Will it fit a 4x8 sheet, between the wheel humps and be able to close the tailgate? I doubt it.
Depend on the size of the sheet of plywood
bed length: 5 feet. I guess it can handle a 5 foot sheet, but I don’t think the bed is wide enough to even handle a 4 foot width, so no. That’s false.
