What I've seen Wanagans used for was just the cook kit, not food. Food went in blue barrels.

The 8 gal action packer would be small enough to stack on another pack and carry using a tumpline. Fits under thwarts very nicely, sideways behind bow seat.

BC, Fuel bottle goes with the cook kit so you only need 1 box opened for cooking besides your lunch items of the day. Colder season trips often have a hot lunch.

Again, Think bigger group and fancier spread. Not your average Q trip. Like M_M said but instead of rafts it's canoes. Big rivers, very little portaging.
