I have two camps at the present and third one in the works.
The first is my full kit. Officer's Marquee Tent, Folding Bed, Writing Table, Chair, Dressing Table, Dressing Box, Writing Box, Spanish Chest, HBC Cassette, Dinning Table, Chairs, Kitchen Box, Cooler, Boxes for cooking and fire kit, Kitchen Table, Duro River Chair (lounge chair), small tables, Shade Awning, Mess Awning, Campaign Chest, Knapsack, Portmanteau, Shooting Box (Armory Box), Rifle, Pistols, Squirrel Gun, Trade Gun, Shot Gun, Dueling Pistols. All of this fits in a Ford Explorer with poles on top. All this takes enough time and effort to set up that it is not worth the effort to set up if I'm not going to camp for at least four nights.
The second is a home made Wedge Tent, Folding Bed, Box, Writing Box, HBC Cassette, Chairs, Cooler, fire kit, Duro River Chair (lounge chair), Shade Awning, Knapsack, Portmanteau, Shooting Box (Armory Box), Rifle, Pistols, Squirrel Gun, Trade Gun, Shot Gun, Dueling Pistols. This is for events of three days or less.
The third I'm still working on is a Bed Roll and Pad,Cooler, fire kit, Knapsack, Portmanteau, Rifle, Pistols, Squirrel Gun, Trade Gun. For a single night or two.
Each camp is designed to reproduce the period conditions of Winter Quarters, Active Campaigning Bivouac, and On the March.
The trick in my mind is taking only as much as you really need and separating the "I've got so I'll take it from I will most likely need it while I'm there." You will be surprised with what you don't really need.
