We do not like to cook inside the van, we found that odors and the inevitable smoke and splatters really make a mess. We carry a
Coleman two burner propane stove and a portable
Pit Boss grill for all our cooking, we also do have a small microwave in the van for reheating leftovers or pre cooked food.
upd: just a small update, still learning on my Pit Boss but find the grate temps to vary quite a bit throughout the smoker. As it requires moving or rotating the meat periodically. And it turns out that humidity is a real problem. Should swap it for a propane later.
