Are there advantages to having gravity down? I know that if you power down with a few tons still in there, your hydraulic oil will get blasted out the reservoir cap.
Just because you have power down dont mean you have to use it gravity with a aluminum box means when it's cold is it isn't coming down again.
So if it's cold and aluminum box the sucker gets stuck up there? I live in Texas but winters get to teens sometimes.
I'm not saying with a aluminum bed wI'll one truck we had need a pull rope put on it. Our new truck has power down most of the time we just ler it coast down
