Cooking outside the RV is fun, gives me something to do, keeps smells out, and reminds us somewhat of what camping was like for us as tent campers for 35 years.
I am an old-fashioned "real" Coleman stove cook. Own 4 of the two-burners plus a couple backpacking stoves. Always carry a two burner with us. Good old white gas is always more economical than propane, only use what you need and don't pay for cylinders.
For grilling, my first choice is the campfire. It still works and the flavor is the best. Remember when a friend who was new to RVing came running out with a gas grill for the steaks. I said what was that for? I had the fire ready for the steaks.
We do carry a small Weber charcoal kettle that we use sometimes. How can a gas grill be real BBQ - that takes wood and real smoke.
But someday I may breakdown and buy when of this flick a switch propane things.
