The hydraulic leveling system has no effect on driving the coach as long as they are all the way up. The air leveling system is another story as the same air bags for leveling and ride height for traveling are used. Good luck with getting the hose replacement, fill up the reservoir and the alarm should go off. Keep us posted.
