Before I sold my Honda Pilot a few months before the pandemic started, it had served me well for hauling rough lumber (8 - 9 feet long) and sheet goods. But I never tried any 4x8 sheet, which I always get it broken down smaller (4x4 or 3x8, etc.) at the lumber yard first. These days, most stores do the cuts for free.
Now, I still have another full-size SUV, just a little smaller than the Pilot. It works well for my lumber needs, as I use ply or MDF mostly for jigs or shop builds, which don't require anything close to even half a sheet size.
For 1/8" ply, it's thin and flexible so my SUV can take the whole sheet.
