I was wondering what kind of flat beds everyone has and why?? Traditional flat bed, spike bed, or arm bed?? What works best and why is that. I have one ranch that is 65 miles from me and it is the one that has the most cows on it, was thinking that I would get a hay trailer that dumps one bale at a time but also might benefit from a bale bed. Either way I need a different bed as there is not nearly enough room for everything in the factory bed. (07 dodge megacab dually). your thoughts??
