I need some help deciding which fueling box to put on my truck. I was thinking about tst or edge ez , is the tst worth the extra money. Which box is easier to egt's in check. I have a 04 3500 srw, 48re with afe pro guard7 intake & torque tube & silver line 4"duals. I tow a 11,000lb trailer in Az. Any opinions would appreciated. thanks Mike
