In Wyoming they don't whistle Dixie. Listen to the northern folks.

Troy, if your '95 LY is like my '94 LY, the storage compartments are all heated (ducted from the furnace). Thus, as long as the furnace is running, all the tanks and the waste valves are kept from freezing.

Here in Canada the winters get really cold (sub-zero temperatures are not uncommon). I've spoken with some fulltimers who live in a motorhome in the Toronto area. They don't use a hose for potable water, the campground that they stay at has special pits at each site where the water valve and hose are actually below the frost line (there's a rope attached to the hose, which they hoist to fill their fresh water tank and then return to the pit).

I remember a friend who lived in a 5th wheel at a campground after his divorce (that will definitely clean out your wallet) - he had put bales of hay in a perimeter around the base of his trailer, and ran the waste through a black PVC pipe properly angled to drain and covered with hay as well. He used heater tape on the fresh water hose and made sure that it too was covered with insulation. It worked for him. Since his was a trailer, he had the local propane dealer put a couple of 100lb tanks up front as well.

Your LY should have an 80lb propane tank, and it can be filled by a propane delivery truck - expect a fill every week or so during the cold season.

Good luck!

Wind Chill Factor

Wind chill factor only affects the comfort level on an individuals skin. Wind can circulate more cold air through gaps and cracks but if there are no openings or gaps you water could care less what the wind chill was. It still freezes at 32 degres.

Leipper, a member here, did some good measurements showing that a parked Airstream stayed above freezing overnight when outside temperatures were as low as 20 degrees. I suspect this assumes non-freezing daytime temperatures and some mix of solar insolation. I traveled 350 miles last October in cloudy weather with temps in the mid teens. Wind chill certainly did have an effect! I used much more LP running the furnace while underway than I would have standing still -- the better part of a 30# cylinder by my estimation. The thermostat was set about 45.

I went to HS in Buffalo, Wyoming (north-central). One winter we had temps as low as fifty degrees below zero. I walked to school that morning and when I arrived at the school the temperature had risen to a balmy thirty-eight below zero. The very high winds are what drives that cold through even the smallest cracks. I travel across southern Wyoming on I-80 quite a lot and and it is very unusual to have a day without winds of 25 to 30 mph. Cold weather RV residents (college students, miners, roughnecks, etc.) usually skirt their units so there is a better chance of keeping the floors a little bit warm (a relative term). You'll see a lot of units surrounded by straw bales that provide a bit of protection although they're not very pretty.

I think I'd opt for a hotel if I had a choice.

Well, not exactly. I agree that "wind chill" is a way to convey how wind increases how cold it will "feel" to a human, but it is also a good indicator of increased thermal transfer due to convection/conduction (conduction, convection, radiation, evaporation--right?). Not only is the breeze blowing cold air through the cracks, but it increases the conduction of heat into the surrounding air by moving the warm air away from contact with the shell and replacing it with cold air, thus increasing the thermal gradient and speeding up heat transfer--like blowing on a hot spoon of soup in reverse, but that brings in evaporation. Let's not go there if it's below freezing. Anyway, even in the absence of cracks and gaps, the temperature will fall faster inside the shell if there is a breeze.

I have to agree that the predominant effect, however, is still the cracks in the window seals and air blowing up into the belly pan area that steals the most heat.

Zep -- (remember, no such thing as cold, just less heat)

Wind chill

I'm sorry but I have to disagree with the not exactly.

I think what you mean is If the area that you want to keep warm is insulated and gets some heat from the floor of the RV the wind will just accelerate the decrease in temperatue but can never make the pipes colder than the outside temperatue.

33 degree outside temperature even in a 100 mph wind will not freeze water.

If that is so, why do I consistently have a layer of white frost on the well insulated roof of my house on mornings when outside temps are as high as 35-40?

Because your roof is looking at outer space which is very, very, very cold. That's radiative heat transfer, which is different than the convective heat transfer which is being talked about here.
