I ve been looking at some 12v pump/resevior combos. What are the cons on going this route for my rear steer project? I assume the pros would be the simplicity of it, Esp due to just running wire for the rear control opposed to hoses. When in a cramped cab this would be real nice. What of the cons? Are the pump combos slow? Are they loud? Can they handle the elements? Or do they just plain suck for what I am wanting to do with it?
