    I have an MFJ 1786 and have operated it over the temperature range here in southern Arizona (-5 C to 45 C) with no problems. We mostly have very low humidity and condensation is not usually an issue. There is little to go wrong mechanically with a gear motor turning the tuning capacitor and gear motors should be OK over most temperature ranges. However, condensation and ice are two known potential problems with gear motors.

    Vertical mounting is generally preferable, but not lower than about one tenth wavelength to minimize ground losses. I have a rotator but rarely use it as it points in the most favored direction of DX signals. The null on low-angle signals can be an S point or more, though. At high angles, it is pretty omni-directional.

    Well OH8STN has been operating STL's from about 2 years now in Finland around the 65° paralel without any issues. The weather is probably similar to what you'll experience in the Alps.
