Is it ok to run savage 21 on sand?
just a tip.
tear down the truck regularly and check for wear and clean it out.
sand sneeking into the wheel hub can give you a suprise later on if not caught soon enough.
I would try to seal up as much of the truck I could. maybe even as far as getting "boots" for the drive shafts and stuff (esp shocks) to keep the grit out. and shield the clutch bell. thats another area were a tiny bit of sand can make your life interesting real quick.
