Too much sand the front wheel drive doesn't need it. We've been driving FWD cars since 1982 and have never put sand in the rear. With 360 pounds in the rear you've shifted the balance of the car to the rear. I only put 300# in the rear of my 4WD pickup by the tailgate. But it's rear wheel drive when I don't have it in 4WD.
2002 RSXtypeS in case you are wondering what I drive besides my Dakota.
