In reply to Fredt:
I do the impact driver with hex head for car camping. It works a treat and I feel superior to anyone with a hammer. Also helps remove them after too.
You can buy tent pegs that have this facility, or some solid screws with wide threads would do too. I could see a need for penny washers for some applications to give a good lip to purchase on. Tent dependant.
We have a 6 birth palace for family camping. Went for a windy week away and ours was one of the few still upright. Pegs didn't pull.
