New RV hitch adjustment

[Jingle]

I was postiñg this picture to get some opinions on hitch adjustment. I would like to insure that I get the height right. I am thinking about raising the pin box on the RV up one set of holes. I would also raise the hitch up but not quite as much. I am considering installing air bags to improve the ride and get my headlights out of the trees. Any guidance would be much appreciated! Thanks!
