Thanks BB-I can give you a good waste of money example on a bell and whistle-On board truck monitoring. As you know, there are a few companies that provide this, some in proprietary form, that have little value to your average buyer. Does the purchasing agent at corporate know what they are? Have they any real experience using them? The most useless and dangerous Bell and Whistle is the one bought thru a national account salesman, sold to a purchasing agent, and installed on hundreds of units bought at one time. Those are the ones they make a pile of money on.
