Looks high to me also. I am fighting that problem now. Few days ago, I put longer rear shackles on my truck... advertised as lower 2"... actual about 1.5". But that did help enough that I could, and did, drop the hitch 1 level (1")... and still have space between trailer overhang and truck bed... and I am about to go out and get it on level ground and check it. I need just a bit above 6" trailer-to-truck clearance to avoid them touching when I back down hill into back yard where I park trailer. I don't use air bags. Wish you the best... I have been towing with the nose a bit high (probably about how yours is in the pic.) till I can get this worked out.
