There areonly 2 of us when we travel most of the time. We just spent a week with only electric for a hookup. If we had anything smaller we would not have had the capacity for our showers that we enjoy. We don't use public showers or bathrooms. We saw a B today in a lot and thought how often we would have to refill and dump. You might have a small apartment but think how much smaller it would be in a Class B. There are even some very good buys on small class As. In my opinion a Class C is either going to have, has, or had a leak inthe bunk bed in the cabover. See how many people have water problems on their Cs. We have had TTs, popups, HiLo, 2 Cs and 2 As so this is our experience.
