They have propane backpacking stoves. I had one when I was in high school. When you compare the weight to all other backpacking stoves, they are heavy. When you compare the weight to two burner car camping stoves, they are very light. They are probably a pound.

Anyways, to the OP. Ramen will be fine for a night or two. Bring some tuna or salmon,or other meat in a foil packet and put it in the ramen. Plan on two ramen packets per person.
