Looking at the updated picture, it doesn't look like it's too much out of level. 15" of clearance at the rear isn't that bad. Bigger question, what is the difference in clearance between the front and the back. That's what tells you if you are level.
For the cost of buying new pin box and hitch, just get the axles flipped. We did it on a prior trailer and it would have been cheaper and actually address all your issues. You likely will need to adjust your hitch and/or pin box heights but that should give you the extra clearance to avoid the pinbox hitting the truck bed rails.
