I use a 4kg (or 4.5kg . . . cant remember).
I no longer use a gas light , and only my Coleman Low pressure Stove.
I can use the stove , morning , lunch , and tea , plus heating water etc etc.
I have used it for 2 weeks , and still didn't get close to running out.
I think 2 X 4kg , would give you plenty , even running lights.
Its been a quite a while , but I'm about 99% positive , we did 6 or 7 days running both normal stove and light , easily on one bottle. I had a second as a backup , but I dont ever recall having to switch over due to running out on a full bottle.
We tended to switch between them. One full bottle , and whatever was left in the other. Run
the part one , till empty , then change. Then refill the empty for next time.
