The entry exit on the Ram will only activate if you activate it so that is not an issue and the truck will not go into aero mode when hauling a load. The owners manual does say to set up a hitch with the air on though but that is all it says.
Unfortunately, with the air leveling activated, the front end will remain at normal ride height regardless of how the WDH is adjusted.
This means you cannot use the front wheelwell height as an indicator of how well the WDH is adjusted.
You will need to use measured axle loads to know if the WDH is correctly adjusted.
This means you must measure the axle loads while loaded for camping and unhitched.
Then attach the TT, activate the air leveling, and make a guess at a good WDH setting.
Then measure the axle loads again to see if you have the desired front axle load.
Repeat with a different adjustment if necessary.
Does your owners manual give any indication of what the front axle load should be relative to the unhitched value?
If not, I would recommend adjusting the WDH so the load when hitched with air leveling activated is about equal to, but not greater than, the load when unhitched.
