Trailer ride height on Great Dane dry van

My company has 30 2015 Great Dane dry vans that all ride at about 13'6.7" . Does anyone know of a way to adjust the air suspension lower and maintain safe ops. Our mechanics refuse to do anything and we have a few tunnels in the state that we can no longer get through. I've checked the online Dane owner manual and it does not have useful info that I can find. thanks.
 
Because you are looking in the wrong place.


Don't look at the trailer manufacturer, look at the suspension manufacturer.
 
Your leveling valve can adjust height , but if you've never done it don't recommend you try. If you go to low can bottom out and take out air bag or plate.
