^That image needs a measurement from the tailgate to the front of the dashboard. And then another to the top of the dashboard by the windshield.

I got the 10' items in there by putting them in the front passenger side footwell, leaning the passenger front seat back and then running them diagonally up towards the top left corner of the rear hatch. Hatch closed fine and barely touched the 10' PVC gutter and downspout.
