After all the research and reviews, getting the weight of the truck with all passengers, finding my available cargo capacity I kept it light with a CURT A20. Less than 130 pounds for the hitch and works with the Sidewinder. Picking it up tomorrow.
The fun part now will be balancing the load to stay under 2500 pin weight. The "dry" weights have the pin at only 1655 pounds with a UVW of 10828. Thats just a smudge above 15%. From our last trailer the most we carried with a full FWT was 1800 pounds, so unless the empty pin weight is wrong, we will be under the 2500 by a couple hundred pounds.
