Extra socket and a long handled ratchet
We love the easy on/off with the Andersen, and as a Type A / OCD guy, I also carry a spare socket and ratchet, just in case I leave one on the bumper or tongue and drive off. (Again!) A quick visit to Harbor freight and a set of 1/2 inch deep sockets is handy for other things, too (lug nuts, hitch bolts, anode rod, heater element, etc.).
