Cold to warm exposure

What effect does a constant cold to warm exposure have on the systems on/in the ford diesel? I have my truck parked outside most of the day then parked in the shop at night (nightshift work). Does that constant temp change have effects on the block itself, fuel delivery system, coolant system, or oil system?

The temperature difference of either ambient indoor or outdoor values are considerably below the values of an operating engine. So while there is an effect, simply starting your truck subjects the engine to a much larger temperature differential. Of course your location (Red Deer, Alberta) may provide a substantial difference between a heated indoor condition and an unheated outdoor condition during the winter. The fluids are more readily affected than the materials but regular operation is preferrable to long periods of non-use.
