Just Cause 3 - Tank Frenzy II Challenge (5 Gears)

Another one I had difficulty with as the multiplier kept running out before I could reach the next batch after the second set of turbines. So I made use of my fully upgraded tethers to pre-rig for destruction. That configuration will pull down the antenna, both fuel tanks, and both groupings of electrical equipment. So any time you are about to lose your 8X multiplier, pop out of the tank, and pull R2 to destroy it all.

Lining up the 7 vehicles before you start instantly gets you to 8X multiplier on low value items.
