This is a Curt A16 slider hitch. Rail mount. I just purchased it this spring, but have decided to try something else. Works as advertised and does a nice job of it. Will drop right into any truck with industry standard rails. For more specs, just Google. Asking $400.
The head is new. Previous one had an issue. Only pulled with it once on a test run to be sure the new head was good. I'm considering an Andersen or B an W. Hence the sale.
Pick up only in DFW, Tx.
