THOR #16783
Palazzo 37.4 winter use

Well we picked up our leftover 2019 unit the other day and are very happy with it. I few items added to the punch list but that was expected. Thanks to all who have answered my previous questions.

Living in NY it does get cold here and we use our RV pretty much year round since we do agility with our Collies. We do a lot of dry camping and have been in some pretty cold weather in the past. My question is what is the coldest weather I can expect to safely carry water in the holding tanks. We will have the Rv's furnace on while it has water in the unit. Also while traveling on the road when do I have to get concerned about freezing. My thought is again to keep the furnace on to help heat the unit.

We are leaving for a trial the end of the week and temperatures will be dropping to mid 20's at night and warming up to high 30' and possibly 40's during the day. I am currently undecided if I will leave it winterized or carry water with me.

Thanks again

Team Collie Coach

I have the same question about our 2018 Aria. I don't have a good answer, but it got down to 24 where I am right now and no signs of any problems.

I had the furnace set to 60, kitchen slide in, water heater on, and cabinet doors under the sink open.

I'm on my way to Wakarusa for a service appointment, so if I do break something I'll be in the right place to get it fixed.

for your water tank, BULK water is very difficult to 'freeze', if that's your concern, and it's very unlikely even in the coldest of times, and since your tanks are enclosed within your basement, which is heated via the propane furnace ducts.

Some of us, though, are more worried about the water left in water LINES that may be more exposed to the outside, since they are more likely to have freezing issues.

We put a small thermostatically controlled 120v heater in the water bay, and let it do it's work if the temps inside really get down too low for too long. That heater is either powered by the Shore Power, if we are plugged in, or the Generator, whenever it is running.

One thing to consider, though, is making sure that any supplemental 120v heating is NOT powered thru your INVERTER, otherwise your inverter could be wasting a LOT of battery power if the Shore Power is lost, or when the Generator is not running.
You can run the power to the Heater from a separate source, such as the 15/20amp connection at the power pedestal at rv parks or campgrounds, or from your home, etc.
If you don't have a separate electrical source, then using this method may not work. Your furnace may be your best bet - especially if you also pull lower drawers and drawer fronts to allow heated air to move around even in undercabinet areas where water lines tend to hide.

Truthfully, I think that if your inside coach is above freezing, you probably don't have much to worry about - your OUTSIDE water hose, though, can be a different story. Disconnect it from your coach overnight, after draining it.

We just went thru below 20degree weather overnight, for over 6 hours, and while an outside water hose froze up for a while, nothing in the coach had any issues - we only ran several 120v space heaters on 750w 'low' settings overnight, and had a temp controlled 120v heater in the water bay, though it may never have come on.

We use a space heater and electric fireplace,when temperatures drop below 32 we set furnace to come on at 68 so it will come on 2 or 3times overnight to heat basement. We have indoor outdoors thermometer in coach with outdoor sensor in wet bay to keep check on it.
