I have a couple qestions about your Cannonball.  One of the earlier posts mentioned you had to bolt down the bed whenever you pulled a trailer.  I thought there was a safety pin that held the bed down.  Is this a hassel?  I will be pulling a trailer frequently with this truck.  What specificlay do you like about the individual controls for the arms?  I wansn't sure if that would be to my benefit or not.  And finally, do the arms float when you are unrolling bales? I like that feature because I don't always stab the bales in the center and that seems to unroll so much better.  Thanks
