We just purchased a 1997 Monterey 36 ft. 3126 Cat engine 46k miles. I do not see any gauges on the dash etc for air bags. Second when its started up do they air up on their own or is there a switch for them? After airbags are inflated which i have no clue since no gauges do i than let down the jacks? After i park the rig i did see switches in the garage area to let air out of bags but i assume i set the jacks first than let the air out. I am surprised there is not much in the owners manual on this procedure. Appreciate the help.
