Wondering if using heater full time will keep water and black and gray tank freezing
Don't think this unit comes with heated pads for tanks
If you are in the rig (or more specifically have the heat on) - things like your fresh water tank should be fine... They are in the living area more or less.
The gray/black - the tanks themselves should be fine - plenty of room to expand even if it were to freeze...
The dump pipes mentioned in the first post would be a concern... If you will be hooked up to sewer - leave your gray valve open so it runs right out. Not sure if the black pipes are exposed at all on your unit.
Disconnect any fresh water lines into the rig if freezing is possible (run off your internal tank and water pump). Protects both your hoses and the supply lines...
(or as Jamie said in the other thread you started on same topic... an option is not to use the water system and stay winterized...)
Note that in some rigs - running a space heater is not the same as running the furnace - as the furnace may have ducting into a wet bay that a space heater wouldn't reach. Though you can use one to supplement the heater - just be sure it doesn't keep the heat from cycling on.
Expect to burn through a LOT of propane if it gets into the low 30's or colder... Typically not well insulated. An 'extend-a-stay' or similar to allow an external propane bottle - or a means to refill might be good to have in mind.
