Tom, My pack load for the lonest trip mentioned closer to 53-55pounds. Sorry, I didn't have a scale. I use a modified pad to help support the loading, I thought I mentioned that, my appologies. Anyway, at least 3/4 of the load was on my hips. I actually got a blister on my hip, but other than that I was quite comfortable. I *did not* like the heat, though.
1.5pounds per day includes the fuel, ie, it is all live load, ie over and above base load. I seem to remember I miscalculated on fuel for the long trip. I brought a two liter bottle, assuming 1oz per day, but by the time I realized I didn't need that much, I could not get rid of it. I had about a half liter left over.
Water is 2-.5liter bottles, I am sure I mentioned that. There is little to no problems getting water in the ADK's. Indeed, most of the time, *avoiding* water is the problem (at least hiking up rt 28-Old Forge to the Moose River Plains area. I saw rain for 10 days straight.) I don't carry water, generally speaking. 'Corse I did loose weight…around 12-13pounds.
I used three ~15 pound stuff sacks to hold the food. Larger and they became difficult to hang. Stuffed full, they became almost a second frame by laying two in left to right, rather than top to bottom, with one over the two, and, slipping my bag/cloths over them. Really, the pack carried quite well, full. I don't care to carry it half empty, though. I really could not compress it and it would squeek to beat h#ll. Never did figure out why…load lifters?
This year, I have only used the Murmur and Miniposa. I carry the Murmur with a weaker pad structure than the Trek, since I can only get about 23-25 pounds in it, it has a very flimsy 3/4" belt. The Miniposa can handle more, but it maxes out at around 35-38 pounds (way over spec.) (I have alo taken to carrying both the NightLite and NeoAir.)
The consumables or live load is all that really changes. Yes, a few ounces more in bear line, a heavier pack (8.5oz vs 1#14,) and a different pad structure (which really doesn't cost any weight) accounts for 2-3 pounds. Carrying UL doesn't really matter that much if you *still* carry 55 pounds.
With the wife, I have been known to carry more. She really enjoys her picture taking. I get to haul 2 DSLR's 4 lenses, cases, Manfroto tripod, a couple smaller cameras, besides my pack, AND, hauling the old boat up to see our loons.
