Thanks Wally I have never check the air pistons and switches will try next. I change all air bags, ride height control valves, leveling selenoids and the coach will stay raise for several days. Also the 12 volts system seem to have no leaks which operate the toleit and pocket doors. What goes out with the 110 pump is off is the step cover, sewer dump, driver seat, and the air supply gauges on dash and in engine compartment both go to zero in about 5 hrs. I have turn both cut-off which are in front of drive axle and it still make no difference. Thanks for your help
