Sorry for the late response but y'all were correct, it was the bypass valve. Got one yesterday and replaced it. I have hotter water than I've had all year!!
We are in a campground 700 miles from home so it took a while to truble shoot it and wait until Monday to find a part.
Again thank you for all your help!! Barney
PS been in the 30's the last two nights so that made the water colder.
