Here is a quote from a discussion on TruckNet about this shower:
Ok it is 6'6" Tall ( basically if you can stand up in your sleeper you can use it, if you can't stand straight up, you will have to see a chiropractor often when you use the shower.
- its 30 inches in diameter, a circle fits most bunks.
-2, 6 gallon water tanks ( one for clean water other for waste ), so don't think you are gonna take long showers, you haVe to do military showers, basically get wet, shut off water, lather up, then turn water back on and wash water off.
-the pump plugs into a standard 12 volt outlet in the truck
-has built in 12 volt water heater
-very portable, weighs 20 lbs without water in tanks
- can fit under bunk or on one side of your bunk, when shut like a suitcase its 8 inches high and 30 inches wide.
I hear it works really well and save loads of time.
