Towing you will be fine, backing could be different. Some times if turning sharp while backing and there is a driveway or you are backing up an incline the truck/trailer relationship will contort and you could hit your cab with a short bed truck. Best to be aware of those situations and inform your spotter also. I would choose a slider or pivoting hitch even though you may never use it, best to be prepared just in case.
