Since it's been asked, here are some details about the interior of an RV. First, note that the one we rented was not a high-end model. And along the way as I discovered things I would have built differntly, I thought about the "ideal" RV and it turned out upon return that Winnebago has beat me to almost all of those things.

But here goes. First, we had a class "C" RV. The class A RVs are basically busses. The class C RV is like class A in that it is a single unit. You can walk from the driver's or passenger's seat all the way to the back without having to go outside. A class B is the kind where a truck tows a trailer -- you can't walk around freely inside.

So the front two seats were just like you'd find in a big Ford truck. Then behind the front two seats on either side were the dinette and couch along the side, and you could walk down the middle towrd the rear of the thing. Both dinette and couch made into a twin bed for sleeping at night. And overhead of the driver was a shelf on which one or two people could sleep. As you head towrd the back, past the dinnette/couch area, you come to the kitchen area. On the left was a refrigerator and on the right a cooktop and sink.

The refrigerator was remarkable in that it could run on 110V AC power when it was present, and when it was not, it switched automatically to propane power. The cooktop (and hot water heater and furnace) also ran on propane.

Heading more to the rear you come to the bathroom on your left and shower on your right. Both are small but fine for a normal sized human. Then finally in the way back rear was a queen bed. It could flip up some to store stuff underneath.

When in transit, people sit in the dinette/couch area and there are seatbelts.

There was roof mounted air conditioner that blew air through the whole RV. It could keep up pretty well with 100 degree external temperatures during the day. At night it would freeze you out. We ran it only two nights and kept windows open the other nights -- we had great weather.

The AC and all 110V gadgets are powered by an on-board generator when traveling and by the hook up at the site when camping.

Hooking up meant the following. First you pull into the site and line things up so that the connections you have will reach their intended destinations. For us, the sewage pipe was shortest, so we usually parked with that close to the sewage port. Then, you unpug the RV from its generator and plug it into the outlet at the site. Hook up a garden hose from a spigot to the RV. Hook up the sewage hose to the dump port. Then you can dump stuff: first the "black water" and then the grey water to wash it down. Grey water comes from the kitchen sink and shower. You can imagine where black water comes from. You can leave the grey water open while camping so you have running water as much as you want.
