I helped my uncle out this weekend, he was going to borrow his neighbors truck for a lumber run, I said lets just throw it on my subaru. A ladder, 20 12' 2x4's, 6 2x6's and a dozen 5/4" planks all fit on without issue. It was just an around town trip, highway can be risky as my cousin found out when the sheet of plywood had enough uplift to yank the crossbars off the rack rails of his Forester. Moral of that story is loop the straps through the windows on big air drag loads. I also have double crossbars on mine to spread the load out a bit more. Threw 450# of scrap 6" C channel up there the other week.
