We are still in the process of researching fifth wheels (and motorhomes) for when we go full-time in just under three years.
A few of the discussions I've seen about showers in RV's (although the topic may have been "boondocking") was that a lot of full timers take what they call "Navy" or "military" showers...turning the water on, shutting it off while lathering up, and then turning on to rinse off...
To be honest, I enjoy taking a resonable shower...just one of the little pleasures in life...
when at a campground, is there a problem taking a resonable length shower?
This is really the first "issue" I've come across with full time RVing..

Thanks in advance for the info...

Good questions!

In selecting an RV, take your shoes off, step into the shower stall, pretend you dropped the soap.  Is there sufficient room to bend over (not squat) and retrieve the soap.  Do you have room, without contorting, to enjoy a shower?  If not, move on.

As to showers in a campground.  As long as hot water flows, enjoy yourself with some sense of water preservation in the back of your mind.

Showers are wonderful!

There's another active thread going on here about Tankless Water Heaters. Basically, with one of those you never run out of hot water.... unless you run out of water altogether. They use propane and only operate when you turn on the hot water, and the second person into the shower doesn't have to worry about running out before they've finished.

You can get some diesel pusher motorhomes with a combination diesel hot water heater and furnace that will give you continous hot water. The main manufacturer is Aqua-hot and they make the Aqua-hot and Hydro-hot units. About a $7K to $10K upgrade. They can also supply about 10 gallons of electrically heated hot water just like the RV propane/electric units.
Remember that RVs are mostly built to be conservative on water usage, a couple long showers and you will have to dump if staying at a water/electric campground.

Military showers are only neccessary when you are boondocking and have a  fixed amount of fresh water and a holding tank for the waste.

If you are in a regular campground with water and sewer hookups, you can shower to your hearts content, to the limit of your hot water heaters ability to recover.

We have a 10 gallon heater and take normal, leisurely showers, back to back, with no problem.

Military showers are the norm when you have either no water hook up and you are running your pump and using fresh water out of your tank (which is limited) and or you are not hooked up to a sewer in order to dump your gray water tank when it gets full. Lots of campgrounds may have water hook up and no sewer hook up.  If you camp with this situiation very much you will learn not to take long showers or else you will need to break camp every day or two just to empty your gray water tank, usally one can refill the fresh water tank with a hose but the gray water tank is a much more to deal with.
