On my 2003 vintage coach, the tankage thermistor is located in the water bay and hangs down on the right side near the water inlet.

Thanks for the response bikestuff. We met while at Newell the end of September. This web site has been very helpful. Thanks for the link to this site.
I need to replace the push button on the circuit board...it broke. One of the threads has a web site for a new gauge. I will do some more looking to see if I can locate a combination outside/water temp gauge.
Thanks again
