The thumper cams are great IF you just want sound, which is what you're after. But chances are you are like the rest of us and can't stop. Bet that truck started with a small static drop then went down a bit more and now it's bagged. You'll get addicted to making it quicker, and the Thumper will be a hurtle. There are plenty of cams that sound just as good but perform 10x better. Go for the one Garrison suggested, his truck is a mean SOUNDING s.o.b.
