I found a post by Emery Stora which may shed light on which valve you have. Quoted below:
"There was recent posting about the temperature/pressure water heater safety valve and someone posted that it was just a pressure valve.
You are both right but it depends on which water heater you are talking about.
The early GMC motorhomes used the Type 1 water heater which was in a rectangular box. This one did use a temperature/pressure valve.
However, the Type 2 water heater which was in a round cylinder case only used a pressure safety valve.

Carey and Emery,
This does help. I have a '74 (square model). The valve may not be new, but perhaps it is still temp and pressure. If so, I may go back to the 180*. I know there is supposed to be a reducer in the output at the head, but I am afraid that when going cross country even a slower flow will get the water "too" hot.
