headache rack with a large sleeper?

am considering buying a large sleeper that has a back door. Do I need a headache rack, or can I run a flat bed without a rack? Looking to run oil field freight which is mostly chains and straps for securement of the load. Imagine I will have to have side boxes for chains, straps and binders, since there is not any room for boxes on the tractor. Thought about a headache rack on the trailer, but have no way to get onto the trailer unless there are some side ladders. If I can't figure away to make the headache rack issue work with all necessary equipment, than I will not purchase the large sleeper. So.....any thoughts drivers.....? Thanking you in advance....Hope I gave you enough info to understand my concerns....!
