How much ballast should I have in the back of my truck? I have a 95 Dodge 1500, short box with plow package (heavy springs in the front, raising the plow lowers the front of the truck by about 1-1.5") The plow is a Meyer's, not sure of the weight and I haven't measured the width, but I think it is 7.5' or 8'. My idea was to line the bottom of the bed with cinder blocks, this would give me weight and a flat surface so that I could still put things in the back. If done right, they wouldn't shift around to much. I have a bedliner so scratching isn't a concern. Anything else that I should keep in mind?
