Funny thing is, on this topic, we are getting a new camper. I had to run my Truck out to the RV Dealer yesterday so they can adjust the hitch for the new trailer. I was talking to the salesman (also part owner) about the oven in our new camper (Old one didn't have one) as I have read that many folks have a lot of concerns about the ovens (dangers and such). Anyway, the conversation led to him saying how many people come in with a "Trade" that has an oven and when being evaluated for it's value they will put their hands up and claim, "I Swear, the oven has NEVER been used." (I am sure it's obvious though). Anyway, he laughs and chuckles, because so many people think because it's never been used that it should be a huge increase in value, when the reality is, that it is not. Many (MANY) folks have them but don't use them.
Unless you are "Living" out of your camper for a long time, I can see that. When we go on vacation, we are looking to relax. While I like to bake (I am the cook in the house), I really don't find it "Relaxing" in cramped quarters and a smaller oven. I was also thinking (like Magic Fanatic pointed out) about how much heat it will generate in the camper/trailer/rv/etc.. I guess if you are in a colder area, it's okay, but most don't vacation in Maine in a camper in December.
