My Coleman stove died on the first night of a 5-day Boundary Waters trip. The debate: should I have brought a backup stove or just a repair kit? | Camping Gear Reviews - Opinions Matter
Hot take: Bring the backup.
Robert is right about packing a backup for the important stuff, but a stove in the Boundary Waters is past important, it's a safety thing. A repair kit is useless if the main part is totally broken, and you can't exactly run to the store. A tiny backup stove weighs nothing and saves the whole trip. I'd never go out there without two ways to boil water.
