Ankie, what floorplan do you have? We have an ElkRidge 34QSRL, and take it to the Colorado mountains to go skiing.
The fresh water drain may be the weak point. It is located between the fresh tank and the pump, it T's off and sticks out of the underbelly so you can drain the fresh tank. Since this pipe is exposed, it will freeze and block water from the tank. We cut an access hole and repositioned this drain pipe so it could be sealed inside the belly, but accessed when we needed to drain.
The other possibility is that the fresh water line is running against the frame. Touching this cold metal can help freeze the pipe.
If you access the underbelly, you can see where your pipes are running and either add heating pipe-wrap, or even just wrapping the pipes with pipe insulation may help.
Two more suggestions... If you access the underbelly, run your furnace to determine where the underbelly heating is concentrated. It may be that it's not getting hot air where needed. We added an adjustable vent to aim the air towards the tanks and pipes better.
Also, the area behind the basement wall, where your pump and many water lines are located, doesn't get that basement heat. Consider adding a lightbulb or small (safe) heat source aimed in that area.
Hope this helps!
