This is the same setup I use. I have about 3 Wolfpacks (stack two behind, then one in front closest to the liftgate). I used the factory tie down point behind the 2nd row seat but it doesn't secure tight enough to the rear tie down closest to the liftgate since its a little off to the right. I used a Frontrunner Stratchit and secured it across the two rear tie down points. Strapped the Wolfpacks down using another Strachit to that. Been on a handful of offroad trips and its very, very secure.
