Is it the same gas? IOW, can the stove that came with the PUP be used with the little green coleman 1lb gas bottles? Assuming correct connections, will it work? We're exploring the option of removing the 20lb tank and switching to a portable stove that burns the 1lb tanks. The question came up more as comparison between old and new stoves, LP vs propane vs white gas... Our pup has no heat and the 3 way fridge is coming out- we just dont use it- so theres no need for gas... a bottle stove would be more versatile. Any recommendations for a good propane stove?
