I dropped the underbelly and tightened the connections and it stopped. Next time at 0 degrees it busted. I unhooked the outside shower in the back and plugged the lines and have had no problems since.
My dump valves also froze for a day during that 0 degree spell.

0 degrees is pretty cold. I have had the fresh water drain line freeze. The heated underbelly is a joke. The heat, when it runs is directed at the 2 front tanks and has no chance of making it to the rear where the fresh water tank is. If it gets real cold I will put a ceramic heater in the basement to keep things warn it there.
