I looked at the books list but I'm afraid nothing struck me as fitting my needs. Basically, I'm trying to figure out how much food and water units would have had to carry with them, and how weather, local availability, and carrying capacity would have affected us before we had horse-drawn wagons and the like. How possible was it to live off the land in pre-industrial eras and still actively maintain a fighting force? How did travelers feed themselves on pilgrimages, and on trade routes?
Surely someone has done a fairly comprehensive study of it and put it into one source?
The only book that I can think of which meets your criteria to a large degree is Alexander the Great and the Logistics of the Macedonian Army, which covers the campaigns of Alexander and uses the best possible estimates of crops, population and water supplies for the time. Engel's calculated calorie requirements and his dismissal of ox-drawn wagons has been contested, most notably by Jonathan Roth in The logistics of the Roman army at war, but Engel's approach and his formula for calculating the distance an army can march without resupply is still valid overall. He also contextualises the problems faced by a general and shows how logistics influences strategy.
Roth, on the other hand, takes a far more general look at logistics and the practical side of foraging, purchasing supplies and carries them. He has detailed sections that break down probable rations, carrying capacity of different forms of transportation, the process of foraging, etc.
While not a single book, the two together should provide you with a good understanding of logistics in Antiquity.
