how would a 300ex do in the sand dunes?

 

OK, they'll get around decently, you just won't be going that fast. They can make it up most hills, you just lose power at the top. At least they are light and have reverse is you get stuck.

 

The sand really robs you of power. If you are seriously going to do dunes with the 300, you should hop up the engine with at least a K&N and Outerwears, header and exhaust (and of course a rejet), plus some LIGHT (Skat-Trak) paddles. If you are running stock tires, air them down for the sand.

 

My wife runs her 300ex all over Glamis. She loves to run up and down OLDS, even though it doesn't go real fast.
