Just move that tractor back if you are bottoming your suspension with a double axle trailor, its quite clear you need to move it further back from the tongue, this should not be a concern using a trailor with a movable weight on it, fixed weight trailors are a whole other issue.

You really should get a weight distributing hitch setup. Helps shift the weight forward from the hitch area. This will drastically help the bottoming out and general handling. As well as safety.
