Well just now logging in I put in redshit haha except that would be scary....
ML drafting is a bad idea-- ever see a rig tire on the road after a blowout?
They are holding aound 90 psi, you wanna be behind that when it goes? Not to mention a 40+ pound mudflap cominjg loose.
But worst of all, you leave yourself zero reaction time should anything happen where the truck needs to panic stop.
As far as saving money the best thing you can do is simply find another area to conserve... obviously not RC

, but largely you can't control fuel prices etc, cut back on something you can control. Buy one less pine air freshener---- you get the point.
