Fire Truck Tool Box - Truck tool boxes may be a popular route. They fit right into your cargo area and allow you to safely store and protect tools any other valuable items. If you're looking for a more complete security option, look at a fiberglass Refrigerated Truck lid.
A few specific factors to consider in used trucks: wear on the current work truck tires, fluids(right amounts and right colour/consistency), check regarding any leaks underneath the truck, and also the colour of the exhaust appearing out of the tailpipe- make sure it isn't white or blue.
More headroom allows the trucker to truly stand within cab. More headroom also provides a nice open feeling to any space; which appealed expertise and my sense for this outdoors. Extra space also allows the trucker to more easily open and close the refrigerator door while he watches sat tv on his new, 24-inch flat screen television, having a built-in DVD player.
