You mentioned your pressure cooker
We haul our griddler, electric skillet, crockpot, looking into getting an electric tea kettle too. Because most campsites, including tent ones have electric included as part of their fee. So we use their electricity to cook with rather than our propane or charcoal. And wood is scare or expensive at a lot of campgrounds. Don’t forget a heavy duty extension cord or two. My favorite has a v shaped head eith 3 or 4 outlets on it.
