Likely won't be the tank that will be affected, but water left in the line from it
to the faucet. Use the faucet well before bed time and it will drain back into
the tank and be fine for morning use in my experience. I have a heater
(Propex) and turn that on first thing in the a.m. and so haven't experienced
any troubles with frozen lines likely in part due to that, but use the water
tank often before the heater has a chance to do its thing with cabin temps
so am pretty sure you won't have trouble as long as day time temps are
as high as your 50's.
