Biggest recommendation I can make for you is to actively flush out all of the sand between the gas tank and the tank's skid plate. If you get sand in there, not only does it corrode but the play between your tank and the skid plate will cause the sand to rub a hole in your tank. Gas tanks ain't cheap
. I know as I had to do this last year...
Also try not to aim at the sand puddles at high speed. When the mud flings on the side windows, it get's stuck inside the door felt and scratches your windows when you open and close...
