Congrats!
FYI, we use electric griddles and an electric skillet for food preparation on the picnic table. Been doing it this way since tent camping days. We very seldom fix meals inside the camper, unless its raining wild or below freezing temperatures. Our current camper has an outside stove. But we prefer the electric griddles.
And about that outside refrigerator. We've had one of these since our pop-up days when it came with an ice box and not a refrigerator. I removed the ice box and turned it into storage, and used one of these for refrigeration. The first on we purchased lasted 15 years. We now have one like this, 2 years old. Keep it on it's back and use for a cooler rather than a refrigerator. We can get more in it that way. Keep it plug in 24x7 and loaded with soft drinks all the time. Easy to move outside the camper, or take with us when traveling:
