I do the same as happyscrapper. I work with several nonprofit thriftstores. I look at the load, put resaleable stuff in the cab/ on top the load depending on what it is. Steel stuff in the bottom of the bed and nonferrous on the top. I have buyers for just about everything that I get that can be resold. I sell to private buyers, trading company's antique stores etc. So the moral of the story is yes LOTS of money to be made at thrift stores:-)
