My last improvement was the installation of my Hard Cab rear bulkhead on sale at Diesel Freak.
With the full upper glass you have no vision obstruction.
I also installed one of the Kolpin RHINO GRIP XL Gun Racks. (One Half of the Two Piece Mount) I tilted the head, and mounted it at an angle with the Head behind the edge of the Passenger seat. This positions the gun at an angle behind the seats. The gun butt just sets on the floor. So far it looks like it will work fine, as long as my dog stays home. His new ride position with the Bulkhead installed, is between the seats on a Furniture pad.
Getting ready for a major wiring project. Hopefully this weekend.
