Water tank question

Question

I keep my 2004 Coachman TT boondocked on my land located in upstate New York with no services. I'm pretty sure there's not going to be long term hard freeze at this point. However, I'm always like to err on the safe side.

My question is, I was considering filling up my water tank half way in preparation for de-winterizing, but not blowing out the lines at this point. If there was a hard freeze could my tank get damaged?

Thanking you in advance for your input.

What do you mean filling the tank but not blowing out the lines? I've always blown after the tank was empty.

Water in the tank is also water in the strainer and pump head. These are the weak spots for freeze damage.

Maybe leave a 60 watt bulb on next to the pump and strainer?

If you only half fill the tank and not the lines, the tank drain might be susceptible to damage but not the tank.

Without blowing out lines just wanted to know if I half filled tank, could it get damaged from possible hard freeze.As for leaving bulb on, no power when I'm not there. Thanks
