At the CG do you mainly use the CG showers or your RV's?

It mainly depends on the situation. We regularly camp at our local state park. No water hookups, so we will use the CG facilities, they are kept pretty clean. We do have limited water in the trailer but we have also showered in there at the park if in a hurry. When on full hook up or water real close, the trailer shower all the time.

I bought it for the shower to be able to use. Especially when hunting down state. We have a water spigot not far and can tote water to fill up the tank.
