That looks really nice, Bob. Congratulations on the new rig.

You definitely, IMO, need to increase the bed to overhang clearance. You said the pinbox was all the way down, but what about the hitch? In the pictures from yesterday I saw the hitch was all the way down. Did you already raise it up? If not, you can just do that.

It looks like the trailer is nose down a bit, so that is good news. It means you can raise the nose by raising the hitch head, and get the overhang clearance you need. Although it is hard for us to see from pictures sometimes, because they can distort what looks level. It's always better to have the trailer between level to nose high, but nose down is not a good idea.

Your truck looks surprisingly level too. I'm surprised how good it looks. But then, you ain't loaded up yet.
