Anybody out there familiar with bale beds? Most people don't even have a clue what they are around here. Anyway, I've used a hydra bed before but the cannonball bed has the dump option, and was wondering if anyone out there has one on their truck. If so do you have electric over hydralic or live power? Does electric over hyd. work ok for you? Mainly wanting an opinion on the cannonball bed but would like to hear good or bad about any of them. Thinking I might get one ordered soon, and still debating which one.
