It seems the question is: "How do I stop the pressure valve from dripping as the water heats up?" not, "My water is too hot, how do I change the temperature?"
If the question is the first one, then there may be nothing wrong. The pressure relief valve will leak for many reasons, the two primary causes are first, the loss of an air gap in the water heater. The air gap allows water expansion as it heats without building up pressure (which causes the pressure relief valve to do what it's designed to do, leak out water to relieve excess pressure).
The second, if the water is too hot, first determine if it's while on propane or while on electric or both. Depending on "which one is too hot", then you can purchase (probably by special order only) a replacement thermostat (set for a lower temperature) for that circuit at a good RV parts store. Don't expect to walk into any "run of the mill parts store" and find someone knowledgeable in water heater thermostats, you'll probably be the first customer asking this year, maybe in the last two or three years, because most people "just live with the too hot water" and either re-establish the air gap to stop the relief valve leak or "just live with that too"....
