Is there such a thing? We’re going with more people and I want to take a bigger pot. I remember large banged up aluminum pots 25 years ago, when going with youth groups, but I can’t find these anywhere. Everything I see is over 4 lbs weight.

I searched 8-10 quart pot for backpacking and found this. . Maybe this would work.

You might try thrift stores.
I pretty regularly see larger what appear to aluminum pots.
One time use might consider renting if an outfitter had something that large.

Better off cooking with two smaller pots and two stoves.

Every boy scout troop or church kitchen has one or 2 kicking around if you beg you may be able to borrow one.

They are only 25-35 bucks at restaurant supply store or even online restaurant supply to buy a new one. Look for 10 quart stock pot. I can find them locally in Kansas at walmart in the latin cooking section(not sure every walmart has this or not, large immigrant community here).

I was able to feed 9 (inclding 6 teenagers) easily with a 6 quart pot last summer. Dehydrated jambalaya and chili both on the thicker side. Are you sure really need 10 quarts?

Here is a stainless steel 8qt at 1.5lbs: IMUSA 8qt Stainless Steel pot with lid
