@Jellybones11, first you should read the thread titled “Alde Freight Train” by DurangoTab. It’s very informative for those who Camp at higher altitudes.
If you had no fresh water in your fresh water tank, if you had no fresh water in your water lines, and no fresh water in the water heater on the Alde, you’ll be fine.
But, if the temps stayed below 32* for more than 2 hours, you may be in trouble with frozen pipes. Check out the winterizing threads in our Resources category for how to winterize. It takes me less than 30 minutes to complete mine.
And the block of ice could just be humid air that froze as it hit the colder ground. You will need to investigate and get familiar with the water pipes in the Alde compartment.
