Some do it with white gas, some people do it with no class. Some do it with propane, some do it in vain, some do it in the hotel, some do it where you can’t tell.
Whatever you do, cooking saves money AND keeps you in fighting shape so you can impress your friends with your road recipes. It also saves sanity because you can approximate real food easier.
So if you’re going to go vandwelling, get yourself a camp stove. Road recipes to come. Breakfast ramen (bacon, egg, ramen) is a fall favorite.
