What likely happened?
Did you try using the FW tank again after you got the CG pipe thawed out?
Can't imagine you froze the water in the tank, so it sounds like something in the line from the tank to the pump or the lines from the pump through the filter and into the rest of the system froze. The good thing is they use mainly pex tubing on that stuff, and its pretty forgiving when it freezes - much less prone to bursting than hard pipe.
On our trailer, the pump and filter are in a space that also serves as the cold air return to the furnace, but they put that stuff in all kinds of places on different models. Some electric heat tape might be the only way to keep those lines warm.
