I will be traveling to Mt Rushmore and Yellowstone in mid September and wonder whether I need top worry about my unheated holding tanks freezing at night. I understand it gets quite cold during Sept. Any help would be appreciated.

Yep ya do! If it only freezes at night then warms up during the day you may be ok. I was camping close the Grand Canyon back in early March. It got down to 19 degrees at night. I went to dump my tank before leaving and it was frozen. So was the drain hose. I had removed the water hose. I just waited to dump at the next camp ground. If you have some way to put a trouble light in the bay or near the tank, that is usually enough to keep them from freezing. You might also try some rv antifreeze. Take Care Steve

Thanks for the reply Steve. Good idea about the antifreeze Guess I'll try that. Thanks again.

The LOW in West Yellowstone was 34 degrees last night. If you can keep your RV in the 72 degree temp range in the living area you may not have to worry about the holding tanks for the next week or so. putting a trouble light in the holding area will help as stated above. funner travelin, Ebs,Donna & Beezer the Beast

Thanks for the reply Bob. I have just checked the 6 day forecast for Yellowstone and they predict the high 20s for the 1st week in Sept. I don't expect to be there until about the 15th of Sept so the going could be rough. I've received some good suggestions though and won't cancel my trip because of cold weather. A trip of 8300 miles should cure my wanderlust. Thanks again for the reply.

It is very unlikely that your tanks will freeze at this time of year, but it is possible. We lived in Wyoming for 18 years and it was very rare for us not to get at least one snow storm in September. But those early storms usually melt the following day, and while it does get below 32 degrees at night, it seldom stays at the low for a long enough time to be any problem with holding tanks. Usually, the most that you will see at that time is a light skin of ice on open water. But it can get well below freezing in late September, in the area of Yellowstone. You can expect high temperatures in the 70's and probably in the 40's at night, with the slight possibility of a hard freeze. If you watch the weather, you should do just fine.

Ahhh, the Black Hills of SD! One of my very favorite places!
I've been in the Custer area at the end of September. The wx is "envigorating" but doubt if you need to worry about your tanks freezing. As Kirk suggested, it would have to be several degrees below 32 for quite some time for the tanks to freeze.
Now the supply line is another story! Not much heat has to be sucked out of that fine column of water for it to freeze. I learned in FL last winter that the weak link in my system was the 90 degree adapter I had at the hose connection on the side of my trailer. That 2 inches of copper easily conducted the heat out of the water and it froze at that spot. Water in the hose itself did not freeze. A couple of socks wrapped around the connector probably would have prevented the freezing.
Enjoy the Hills, and be sure to have lunch or dinner at the Alpine Inn in Hill City --- not far from Mt. Rushmore. You won't be sorry! Regards, Keith

We were in the Black Hills last year at the end of Sept and had no problem with water freezing. The nights were cool...low 30's...but the daytime highs were in the upper 60's-low 70's. But we all know how the weather can change! Have a great time!
