What could cause this???

I've had a ST29SS for 4 years now. Last camping trip the Attwood HWT worked on both electric and gas. This camping trip neither are working. There's water in the tank, the fireplace HWT switch is in the correct position, and the switch for electric is lite. Tank is ice cold. Gas burner also won't light. Everything else in the trailer is fine. Thanks for any ideas.

Sounds like you may need to start tracing voltages. The easiest is at the water heater itself but also include the wall switches and fuses/CB's. Use caution when checking the 120v side.
