I have a few tips:
Drinks Esky - I freeze about four 600ml water bottles and a 2Lt empty cordial bottle. On those hot days setting up camp its nice to have an ice cold bottle of water. I also make big blocks of ice from man size lunch boxes. It lasts for about three days
Peg Mallet/Lifter - I bought a cheap rubber mallet and screwed a heavy duty cup hook on the end of the handle. However, I am going to buy a Coleman Peg Hammer/Lifter
Double-sided Velcro - Its great, cut to what ever size you want, can be moved and when not in use it wraps around the CT poles. Its better than the plastic ties. Saves money, landfill, and cut fingers.
Equipment Bags - Write on both sides of the bag what is inside and/or how many items are inside.
Shade Cloth - Make your own equipment bags for pegs, ropes and poles. Make sure you double layer the bottom of the bag for strength. When you have wet, muddy poles, pegs or ropes wash down the bag with the hose and hang up to dry.
