I found that out that hard way. A 50 mph speed limit, a wet road, a fast stoplight, and touchy brakes on a truck you haven't driven before. Nice way to start a jacknife, and almost hit a car due to not enough ground pressure on the the tires.
I experimented with puting weight behind, ontop of and against the bulk head. To me putting the weight up front worked just as good as on top of and way better than behind the axle. It also left the back part of the bed open if I wanted to put something in it without moving the rock hard sand bags.
