Will Holding tank contents freeze in winter?

[wiepie]

Hello All,


We have a Winnebago Chieftain 1987 and we are wondering how frost-proof these RV`s are?
Does anyone have experience with that?
I am mostly concerned about the water tanks below the chassis.

Unless your tanks are housed in a heated compartment or have electric heat wrap, the contents are susceptible to freezing.
