Extreme temperatures (cold as well as hot) do tend to create difficulties for electronics, motors, gears, lubricants, and related components. And, as you more or less noted, this is really much less of a telescope issue than it is a mount issue.
In both worlds, very cold and very hot, it tends to be wiser to avoid so-called "telescopes" that are "married" to their mounts. To me, a telescope is basically just the optical tube assembly -- a separate entity from the mount.
I live and observe in what is sometimes the other extreme: My record cold observation was with a raw thermometer reading (not factoring in wind chill) of minus 50 degrees F. That can be every bit as unpleasant for many mounts as can very high temperatures. Yet, telescopes can mostly handle both extremes.
It seems that many make frequent moves during their lives, but if one settles in one location long enough, one learns how to deal with the extremes in that location. This includes purchasing suitable equipment -- equipment that will work for you in that environment.
There was a time when I would go out on every moonless, clear night to visually hunt comets. Many times, I swept for comets when the temperature was in the minus 20s. Many mounts would quickly fail to operate at such temperatures. But there are other mounts that will function just as well at +120 degrees as at -50 degrees as at +70 degrees F.
If you're going to be living in that location for the long-term, I suggest making more appropriate mounting choices. Simple, manually operated mounts are pretty much immune to temperature extremes.
This (100% manually operated) mount, without go-to, without tracking motors, remains operational for me at any temperature in which I care to use it.
But even more reliable is a mount like this one:
Both of the above mounts, combined, cost less that $500 -- with one purchased new and the other entirely homemade. Note that the telescope in both photos is the same telescope.
