unanticipated freezing temps

How true. Four-wheel drive works better than four-wheel stop.

Problem is a lot of folks around here don't really understand black ice and how it can form, and how incredibly dangerous it is.

I love it when there is a little snow and all the people with heavy duty pickup trucks with absolutely no weight in the rear end can't understand why they great vehicle spins the rear tires.

Yeah, too many people think that owning a four-wheel-drive vehicle buys them an exemption from the laws of physics. It doesn't work that way.

They need to learn that when it's slick there is no substitute for slowing down and keeping their foot really light on the gas and brake.

Things are getting interesting here in the Allegheny Highlands of WV with this latest cold front. Snowing, temps dropping, wind howling. Expecting wind chill of maybe as much as 50-below.

A guy has to respect Mother Nature, she can cause a heck of a lot of grief.

I wouldn't sweat temps in the high 20's, especially for short duration (overnight). If I was using the TT, I'd fill the water tank full and just run the taps every few hours to make sure the pipes are in good shape.

It's -20f right now at Rancho Westend but I'm parked, winterized, and don't have any plans to even leave the house.

Wait until you see us try to drive / tow on black ice!!! . . .

I won't laugh at anyone's fear of black ice. Black ice almost cost a good friend his life.

But I've seen southern drivers on an inch or two of snow and it's usually been pretty bad.

Hi Wayne,

Great information on the energy loss required to go from liquid water to ice. Thanks so much.

The folks here probably think btu's per pound rather than calories per gram.

The 80 calories per gram translates to 144 btu's per pound.

The OP described a situation where the air temps were expected to get down into the mid 20’s for 1 or 2 nights, with daytime temps in the 40’s. That is neither cold enough nor long enough to cause a problem. Not even close.

Water at 32*F needs to shed an awful lot of additional heat, 80 calories per gram, before it turns into ice at 32*F. That’s the same amount of heat it had to shed to go from 176*F to 32*F. That requires either very cold temperatures or a long time period.

I’ve spent many dozens of nights camping in that kind of weather with no problems. And my TT has no special cold-weather features. I would not give it a moment’s thought.

But, we’ve all got to find our own comfort level.

Ok, got the shore water working, so seems like my on board pump is shot and not pumping versus frozen pipe. It only makes a humming sound so guess what I will be doing today!

If just humming it could be sucking a little air. Make sure the inlet hose connections are tight.

Here in NJ we got down below zero Friday night and will again Tuesday night. It has been a brutal winter already.

We're seeing the first teens temps and four or five days below freezing we've seen for 10-15 years - which will extend as far south as San Antonio.

Yes, we are overly cautious.

Fixing things is expensive and a huge pain.
