Weight Distribution hitch s/u with air bags

Made a deal today to buy a Coachman Freedom Express and have never pulled a trailer since we installed air bags.
Any advice appreciated. Do we set up the hitch as normal then add the required 10 PSI ? Or would we be better to leave the 10 PSI in while adjusting the hitch?
Thanks,Mike

    Sorry Skip I need the bags for my Shadow Cruiser slide-in camper
    I did have my WD system set for my Cub Hybrid but haven't pulled the Cub since I got the slide in this spring to use with the boat trailer.
    Grandma says that's gonna change so we made a deal for the Coachman.
    I believe I did a fair job adjusting the WD for the Cub but don't know what to do about the minimum required air pressure - add it before or after the hitch is adjusted?
    Thanks,Mike

    I put air springs on my one ton when we were towing a fifth wheel. Have a travel trailer now. When we picked up the TT and had the WD hitch installed and adjusted, the dealer's service dept. told me to bring the truck with the air springs inflated to whatever pressure I would have them set to for towing. Used 30 psi for the fifth wheel, and that seems to work fine for the TT as well. Truck and trailer is level, and the ride is good.
  • Thinkin you should leave the psi in. IF you properly adj the hitch, and then add psi. You would then cancel the effects of the WDH .
    Remember. While air bags will level the TV. They do NOT return lost weight to the front steering axle. So you can be level, and still have sway induced by loss of steering control.
