Thanks I'll try to get more information as I can get it. It confused me because all the information I can find is with the valves in the rear. I do know when I lower the rear it exhaust the air form one the valves in the engine compartment and if I lower the front it exhaust from one in the front compartment. So I assume the front set controls the front and the engine compartment set controls the rear. I can't find what controls the travel suspension. The level switch on the dashboard is only on/off, no switch the actually says travel.
Thanks
