How long is your trip? Are you going to have a truck to hold several coolers?
4-5 days in salt ice will be fine. Bottom ice, belly ice, top ice, drain often. I hate fish bags, but you're supposed to be able to ID each fisher"s catch. Repeat in the next cooler if you get that many. Bleed and ice your fish in the boat to get things started properly.
There is proper salt ice facility downtown PA at the docks to get you started, then I don't know (I fish the Ukee side). McKay Lodge I think.
