I have 1000W inverter generator as well. Even I have big Honda for years, when fellow forum member gave a tip about HD having them on sale for $150, I just could not refuse to buy it ;).
For years I have propane burner that screws on top of small cylinder.
Used it on the boat, but one time, while cooking on the beach my wife kicked the pot over.
So potatoes were extra crispy that day . Only lately I found I can buy enlarged shoe for the cylinders.
Even I have electric cooktop, I never used it in RV. I found out my favorite is toaster/oven, where I can bake kielbasa, zucchini, onions and tomatoes, while potatoes are easy to bake in microwave.
So I plan to carry those 2 units in this van, although they will have to go under the bed for travel.
I already build smaller cabinet on driver side, who will have to serve as wardrobe, leaving narrow side for shelving. Maybe small appliances will fit there for travel and countertop will be good place for using them.
