After spending 21 years in the army carrying all my gear in a rucksack and/or aidbag, I think ( as other veterans in here might as well) that the sheer weight would be difficult to manage on the furca pole. 1 gal of water = approx 8 lbs. I dont know how many gallons could go into both carriers but thats probably up to experimental archaology to tackle....
