There's no shortage of pros/cons to consider. We use our RV all the time.

The less you use it, the more it costs per trip (if you divide the depreciation by time spent using it), which some people see as a reason to get hotels.

For week-long events, hotels are hard to beat (someone else cleans up after you, unlimited water for better showers, etc.).

For cross-country trips, the gas in an RV will kill you. Here, multi-stacking and sharing costs is the only good solution.

10 mpg in a 28-foot Class A??? Wow, what year, engine, make and model is that?
