I've seen it done a couple times so obviously it works, but I was wondering if there are any problems with using just one bag in a rear set up. Would one bag have a harder time lifting the back of the truck since it has to lift more weight? Also what about the ride if it was used in a lever type set up. Would it work any better or worse than your standard two bag set up in the same situation? And yes, I know about keeping the axle centered, I have that figured out already, and no, I don't care about hitting sides .
