Guess the wife and I, just don't use enough hot water at one time to make it an issue. If both want to shower one after the other I simply turn the gas heat on with the electric. We do have a 10 gallon heater. Otherwise for washing dishes or the typical face, hands and shaving we have plenty of hot water. When boon docking we simply only turn on the water heater when it is needed. To me seems simpler and certainly less expensive than going with a tank-less header.

LadyFritz,
I this is a very well written post. I found it very helpful and i had already done considerable reading on the tankless.
The bottom line for me is that my wife is not happy with a "Navy" shower and we have a KZ Escalade with a 12 gal tank. I nice long hot shower is a great way to warm up in the winter, especially when you live full time as we do in our rig. We will be getting a tankless. I am leaning strongly toward the Precision Temp RV500s because it has more sophisticated temp controls and should pop right in where my current heater is. I have plenty of extra room there if I need it.

[QUOTE=jcthorne;961000]
In the 5 yrs I owned the RV500 I had very few satisfying showers.
========================================
Well, at $1,000 for a RV500 that is not what I was expecting to hear. Thanks for the insight. I will keep looking into this.

I've seen several people say they liked the RV500 and only one who didn't (that one claimed it was an RV500 he installed but the symptoms he described sounded typical of the Girard so the jury is out on that complaint).

The fact that the RV500 runs only on propane bothers me a bit. I had someone mention that the "16" gallon Atwood Exothermal model (a 10 gallon model that heats water hotter than normal and uses a mixing valve to mix it with cold water to give the equivalent of 16 gallons) gave long showers but when I tried to pin him down to the length of the showers and the recovery time when on 120v only, I never got a response. Anyone know anything?

My parents ordered a 1958 (Yah, that long ago!) 17' KenKraft TT, they specified a tankless water heater. KenKraft used a gas unit made for foreign stick houses. When they sold it years later the water heater was still working fine. Not that they didn't have troubles (frozen water pressure regulator), but it could be fixed. It was plumbed into the sink and shower too.

Would it be possible to switch to an On-Demand? Yes, in fact at least one company makes a "Drop in" replacement for the standard RV water heaters.

Other options:

You can use a cut off valve (Should be one in the shower head but if you don't have one go to Lowes or Home Depot and pick one up,, Just tell 'em "Shower cut off valve" in the plumbing area and they will point)

You can also get a 10 gallon heater in a six gallon "hat" (Yes, Attwood figured out how to put 10 gallons of hot water in a six gallon can) they do it by heating the water way hotter than you normally do and then mixing in a bit of cold water as it exits the heater in case you are wondering.. I do not recommend this unit normally because there are several things that can go wrong that can not go wrong on a regular heater.

Downside of "on Demand" is that they eat a lot of energy very fast. This means you are going to have to run 'em off Propane only. No electric opiton. Or if electric you need 220 volts (50 amp service) no 30 amp parking spots.

Another option is to install a higher temp thermostat (Easy on Attwood, don't know about other brands) and mix in more cold at the faucet.

If your heater has both gas and electric heat.. Use both at the same time (helps) as well

What do I do: Usually, Park shower instead of Motor Home's Better water flow.
