So ... IANARS (I Am Not A Rocket Scientist) ... The lunar night is about 2 weeks long. The night-time surface temperature is about -230 C to -150 C. I'm not sure how long it would take a lander to cool down at local sunset, but it might be pretty fast. That kind of cooling can create stresses and actually break mechanical connections or electrical components. It's a lot warmer at about 1 m under the surface, but you have to get there somehow.
