You're right...it is subjective. By long in "RV speak" I mean any thing where you run the water continuously more than to wet down or rinse off. We turn off the flow for lathering & shampooing...this is often referred to as a navy shower.

Actual time can vary depending depending on whether you are using the water pressure from city taps or pumping out of your tank. Regardless...it's a short shower. This is why we went with a tankless insta-hot water heater to use in our Safari while camping with hook-ups...that way we have unlimited hot water.

Well, you have 6 gallons of water that is generally 160 degrees or so. Add in about a third cold water to get a comfy warm shower and by my poor math that is about 4 minutes straight running with the typical 2 gpm shower head.

Four minutes is longer than you think...

This is where it gets fuzzy. Sometimes I add "cold" water thats 90 degrees. Sometimes its 35 degrees.

One thing good is it doesn't just get instantly cold. Its like at home where you gradually move the mixer towards hot as it runs out.

Taking short showers with the faucet off when soaping up will prevent you from getting a cold shower. For all other purposes like dishes, shaving, washing hands etc. 6 gal is plenty of water.

So, what is considered a "long" shower? That seems like it could be quite subjective to me. Has anyone actually done some loose timing about how long of a shower can be squeezed out of that tank? Also, I'm curious to know if anyone has found that one of those Oxynegenics (sp?) shower nozzles helps extend the length.
I installed the Oxygenics last fall, just before putting the AS in storage. I did it based on this comment: Dreamstreamr Odyssey Chasing 75 Degrees

The price has come down so I went ahead and purchased it. It will be interesting to see how it does.

If you run the hot water constantly you will get about 5 minutes before it goes cold...the higher the gpm of the shower head, the quicker the hot water will exhaust. Turning the water off while soaping up and lathering conserves the hot water to where you can have plenty of hot water to rinse yourself off. The break also helps the heater re-heat and allows the next person to shower without having to wait for the hot water to come back. My shower head is the original and it has a gate valve on it that makes it easy to turn the flow on and off without losing the hot/cold mixture. My previous box trailer had a button on the shower head that you would press to stop the flow and then when you re-established the flow you would get shocked with extremely cold water for a couple of seconds before the hot water mixture returned. My original shower head used to always just trickle water even with good pressure. Before buying a new head I finally took it apart and found a flow restricter inside it, which I happily removed along with 30 years of water deposits and now it works like it is supposed to. It has 3 heads, shower, faucet and massager. Removing the vacuum breaker also helped increase the water flow to the shower head. the only thing I don't like about it is its heavy because it has brass and it's shape is not conducive to it being used as a shower mounted on the hook the ceiling. Because of the ceiling angle and the long shape of the shower head, the water ends up spraying straight down instead of towards you in the direction of the bench seat. It works better if you hold it in your hand to wash and rinse and to mount it on the lower hook intended to fill the bathtub. It took a little practice for this 300lb 6' + tall guy to learn how to maneuver in the rear bath. But I'm a pro at showering in the airstream now and losing about 50lbs helped. They aren't made for big people. Those of you with 70's era rear bath models know what I am talking about. You know its time to lose weight when you have to squeeze yourself on and off the toilet as there is not much side room for "overage."

really 6 gallons of h20 is more than enough for a good shower...unless you went to the cooler long after the sun had gone down,for another wobble pop, only to realize the local skunks beat you to it. or fell down in something you could only describe as kinda wet and gelatinous that seemed to try to grab...never mind i've probably said enough...yeah 6 gallons is generally good enough.

Wow, this is the most definitive thread I've seen yet on water heaters. Personally, I've had both 10 and 6 gallon models, and I'd have to agree the 6 is enough. I'd HIGHLY recommend getting one with electric and gas, especially if you're camping with full hookups a lot, as it can really save on the propane.

vvv This is good advice too...

Another alternative still !

We swapped out our 6 gal. Atwood gas fired HWH for an "Atwood XT" Combination gas / electric a couple years ago.

It somehow magically makes 6 gallons turn into 9 !

Cool setup so far and a clean and easy install.....

"Using the principles of heat exchange, Atwood XT® 10 gallon models provide the equivalent of 16 gallons of hot water at the same size and weight as standard Atwood 10 gallon water heaters. The 6 gallon Atwood XT® provides the equivalent of 9 gallons of hot water at the same size and weight of standard Atwood 6 gallon models. Choose propane or propane/electric models, all with Direct Spark Ignition for easy lighting. All models install in the same cut-out openings as standard Atwood models. A winterizing bypass is already built in."

The size and design of travel trailer shower compartments have been optimally matched to their water heaters to ensure you will want to get out, before the water runs out.

If it is not too hard to run the 110 so you can have a gas/electric you can run both at the same time and recovery time is less. Then make sure you cut it off while soaping up and 6 should do it.
