Our camper shower is huge, and we have a 10-gallon water heater, but we prefer to use the campground's showers if they're not busy and it's not chilly out.
The showers are close, clean, hot, 100% private and the water pressure will take a layer of skin off. Way better than my house shower. I look forward to it every weekend. We're also seasonal campers and know what to expect. We know the cleaning schedule and the best times to take an awesome shower. The other 7 seasonal families do the same thing for the same reasons.
