Cold Weather Camping

I should have searched this topic before I wrote this…there were some good pointers; any further insight would be appreciated!

Plan on taking 2009 2350 on a hunting trip. Will have 110 power. The fresh water has been emptied and hot water heater drained.  I have tank heaters.  I plan on flushing the toilet with jug water.  I am assuming that the tank heaters will be safe with any waste water that’s in them.  The living area will have heating.  Should I run a little antifreeze though the macerator to be safe.  What am I over looking?
Thanks for any suggestions.

Unless you have tested, and know for a fact that both tank heaters are working, and depending on how long you plan to be there, I would put a gallon of RV antifreeze in each waste tank, even if you don't plan on using the Grey tank.

Don't forget to put RV antifreeze in the 2 sink traps and shower trap also.

If going during the next few weeks (not during the dead of winter) your PC is deigned to operate with full plumbing functionality.  Just make sure you maintain interior temperatures in the low 70's and all your outdoor storage compartments are always fully latched.  All fresh water plumbing and the fresh water tank are inside the heated interior.  It is the waste water that is outdoors, hence the need for the two waste tank heaters.

With our 2007 2350's particular arrangement of mechanical features, if we were camping in freezing temperatures consistently below 20F, I would add two 4" round vents on the side of the bed platform, placed as far apart from each other as possible, then mount a switched 12V computer fan into one of them to circulate room air under the bed to assure the fresh water tank and related plumbing stays warm enough.

The outside shower on our 2350 is inside the bathroom vanity and it is vulnerable to freezing.  I would remove the shower hose with head, then stuff insulation inside it to protect the faucet in there from freezing.  I would also add high and low mounted 4" round vents on the side of the vanity cabinet to circulate warm air via convection within the vanity.

These 4" round vents are sold at Home Depot.


With shore power available, it goes without saying that a couple of 110V 1500 watt cube heaters will be very handy.

Thanks to both Don and Ron.  I will take your suggested  precautions and apply them.  It’s Montana in late November and I need to be prepared for every type of weather imaginable.  The unit should be out of the wind which should help.  Thanks again for you advice.

It’s Montana in late November and I need to be prepared for every type of weather imaginable.

We spent much of the month of September in Glacier NP Montana.....beautiful country.

We had morning frost in early September outside the park near Many Glacier.  We camped in a private campground near Babb called Leaning Tree which had 20amp service.  It was nice to run the cube heater during the night at 500w or 1000w pending how cold.  I imagine today it would get cold enough to have extra precautions in place.
