You are going to have a kitchen one way or another, inside or outside, unless you only eat at restaurants or eat packaged snacks. We cook outside almost 100% of the time. Even when we had a motor home cooking was outside but food prep was often inside Outside or inside you have to bring "stuff" that takes up space someplace.
You can adapt to have food that won't require cooking or prep. Eggs & Sausage on the griddle, or bagels & sausage sandwiches in foil over coals are good for breakfast but so is some yogurt and/or granola. Hamburgers on the grill with baked beans or ham and cheese sandwich with some chips. Or you provide small electric alternatives such as toaster oven, sandwich maker, hot plate, or electric skillet and make sure you have power.
You do need to have food that allows you to go with the flow because sooner or later weather or situation will come along that will make outside cooking unattractive option. Not all Walmarts or rest areas, or truck stops are going to be good with you firing up the stove on the tailgate so you have to plan for that situation. Rain and high winds may make outside canopy a poor idea unless you think sacrificing a canopy to the wind makes mother nature take pity on you and brings on good weather.
Must be able to make coffee so no one gets hurt by the crazy people in the little white camper but that can be off of battery
or just enough stove time to boil water to make a batch to store in the thermos. Decent instant is better than random slaughter and blood curdling sobs and screams. Tea will work in a pinch.
If you ever have had a flooded Coleman liquid fuel stove then you will know why they say to only use outside. Unless to signal a ship at sea for rescue, several foot high flame good for that too. I think the lack of low oxygen
shut off and minor explosion potential from propane leaks
are probably at least part of the motivation. I have stuff from back in at least the 60's that has that warning. On the heater I have always wondered what do they think I'm going to use this for outside? Maybe it has to do with using them in tents?
People check their RV propane
system for leaks
, they also own them in the event there is a leak any damage is on them not Coleman. The joints in an RV gas system are not screwed on and off the way a 1 lb. propane
bottle is, who checks their propane lantern for leaks
with soapy water every time they change the bottle? Not saying it will kill you but using a lantern for heat or a stove inside certainly does carry some risk. If nothing else that hot lantern will do some serious damage if it falls over as can the heat from a stove grate after it gets hot.
