Below freezing temperatures. What do I do?

[scottkeen]

I'm going to be camping for 4 days in below freezing temperatures. Besides head for warmer weather, what do I do?



I'm taking my 2011 Montana Mountaineer 347THT out for 4 days and for a couple of nights it will be below freezing, around 18 degrees at night. It's supposed to get up to the low 40s during the day. I already paid for the reservation, so don't want to cancel...


I have a couple of questions:


1. How do I tell if my RV (I purchased it used) is insulated for 4-seasons?


2. Are my holding tanks insulated, heated, or heated by running the LP furnace?


3. What can I do to prevent freezing to the holding tanks and the water pump?


4. Would leaving the 12V 60W incandescent light on in the water hookup panel be a good idea to keep that area warm? Fire hazard?



5. Do I leave the gray tank valves open or shut? If the valves are frozen shut, how do I unfreeze them?



6. Do you advise to put water in the fresh water tank and use the water in the tank, and disconnect the water supply hose? I don't have a hose heater tape and don't plan on camping in cold weather like this again.


Also, any other advice on RVing in these sub-freezing temperatures for these couple of days is much appreciated!
