I did have the height in a file, but it was deleted after picking up the new Truck. If memory serves me right, I think it was at 58"-58 1/2" the new truck is the same and hooked right up to the 5th wheel without a problem and everything is level. I'm not running any air bags etc. because the GMs have a slight forward rake and once the pin weight is set on the hitch it just engages the helper springs and levels the truck. I don't worry about the head lights because we avoid traveling at night anymore.
