i used that model Peak on canoe trips in the 80's and then moved to the Feather later on.they are a bit heavy but the tank holds a lot of fuel and they can take a beating and still run fine.
look around for the square case/cook kit and you will have all you need in the way of pot set.you can get a fine simmer with that adjusting lever and don't forget to swing the legs out,i have put a 3 quart pot on mine.
if you have never used one my advice is be careful on the pre-heat.if you flood the burner you will get a real fire ball.
in cold weather i use a bit of fire paste under the generator.
