Tie-down systems performance/safety vs cost

I have a similar truck as the OP, a 2012 GMC 2500 4x4 6.5' box. I've been using HappiJac tie down system for 8 years now. Don't believe the naysayers, the HappiJac system is frame mounted through the box up front and the rear bumper anchors also have a bolted on support from the frame. There is also a convenient load centering bar with centering bumpers to help keep your camper centered while loading and while hauling your camper. You can use the huge savings on Qwik Load or Fast Gun tie downs if you want. The Torklift front anchor points will block your fuel door and require you to loosen the front tie down every time you fuel up.
