Thanks Duck, good to get a second opinion. There were plenty of videos online, but they all seemed to be concerned with rear axle springs on pickups, and there was nothing about front springs on an RV. I started at just 25psi, but I've upped them to 35psi to see how they do. Airlift say max psi for the 1000 is 50psi and min 20psi, they must have a min psi as they can collapse and be damaged if totally empty. I must admit, I did get my mech' to fit them, more due to the weights involved than anything else, I don't have the heavy-duty axle stands he has. He said they were pretty straight forward and I asked him to fit the 2 Schrader valves, for pressure adjustment, just behind the hood.
Oh yeah, my bad, my Axis is a '15 not '14
