as much as I can fit in the Jeep and sill use inside the Jeep. Never weighed it, just know it takes too many trips from the house and back to get it all loaded. Everytime I load up for a trip, I say I need to cut back on stuff going with me...... I say they same thing everytime I unload it when I get home too. But you can't use the equipment if its not with you.
Since I have to travel by air, I take what I can carry on the airplane - 4x5 field camera, 3 lenses, QuickLoad holder, 35mm with one lens attached. Tripod, film holders and extra lens for 35mm go in checked luggage. Usually 2 to 3 boxes of QuickLoad film and 5 rolls 35mm - sometimes a box of cut film as well. Perhaps 40 lbs or so - I have to be careful, the max the airlines allow as carryon is 22 lbs.
I've never weighed it and am afraid to. I wouldn't carry everything myself and my wife balks at carrying the little (I say!) that I won't. Where the going isn't too rough my Ruxxac cart is very useful. Where it is too rough for the Ruxxac I walk in, decide what I'll use, walk back out, and walk in with no more, sometimes less, that what's needed. My wife says that walking is good for me.
The most I've ever flown with was: Pelican 1500 with 2 Nikons, 2 283s, 5 lenses; Tundra Sea King 821 with Beaulieu 4008ZM2 and 5008S-MS, their zooms, 4 prime lenses, filters, ...; 30v battery belt (home brew, 15 2v lead acid cells) with spare cells to make charging easier; tripods; Omni Light; 40 rolls of S8 film, much 35 mm still.
I carried all but the tripods and the Omni on board. This on a trip to Paraguay in 1992. Those were the days! I can't imagine being allowed to take the battery belt near a plane nowadays.
