This is an interesting post.
We tend to build our TDs (in my case) with all the creature comforts; Bed, stove, fridge, TV, radio, electric fan heater, AC, lights etc etc etc.
Then we turn around and have a contest with ourselves as to who can pack the lightest....
I am like most, a pair or two of pants, couple pair of socks and underwear, pair of shorts, couple of tees, a couple of towels and maybe if I get really carried away some flip flops and a bathing suit.
And FOOD lots OF FOOOD.
My wife: well lets just say she gets the other 3/4's of the storage space.
The stuff below is always on the trailer and seldom needs to be packed, just replenished every once in a great while
Matches, First Aid kit, snake bite kit, bug repellent, blanket, rain coat, paper towels, napkins, 4 knifes, forks spoons, cups, plates a spatula and a big spoon. Some herbs, (who is that guy?) salt pepper, coffee, sugar, cream. I also carry a big sharp knife in case the steak is a little tuff.
Just in case of emergencies tucked far in the back: Ax, fold up fishing pole, flare, two sections of rope, extra tarp, extra water, freeze dried food, small shovel, Fire extinguisher, fire blankets and some other ODs and ends such as flashlight, compass, batteries, extra bulbs for all the trailer lights, small box of tools, electrical wire and electrical connectors and a can of fix a flat, maybe one day I will pony up for a spare.
And last but not least because I have my 12 year old daughter with me:
Guns, axes, knives, sword tear gas, tracking device and a big chain with a ball....

Just kidding
