I wasn't aware that there was another Scamp
5'er deluxe so close. I'm up in Prescott. As to the noise of your water heater I have found the same thing, only when the flame is on to heat the water. It does heat quickly, and have found that it will stay hot until the evening dishes. Because of this I only light
it in the mornings before breakfast and when it cycles off I turn it off. if you would like to compare notes, PM me and I will send you my phone number.
My wife and I drive through Skull Valley often heading down the hill. Continue to have fun with your trailer
