We are getting setup at our site at our winter workamping location in N. Ft Myers, FL. I took a few photos of our Gooseneck ball and Anderson Ranch Gooseneck Adapter.
Our flatbed truck bed is 42" high at the rear or 40" compressed with the weight of the kingpin on it. The distance between the flatbed surface and top of the kingpin is ~11" with our Excel 33RSE RT pulling completely level. Our pinbox is installed into the upper-most position possible.
