Doubtless you may get some help from the real bush-pilots on another forum, so here are a few snippets, whic may be open to flaming!
Check the manufacturers h/b for helpful hints/ oil /hydraulics etc
check drain fuel tanks to be sure there is no residual water /sediment etc. check all hoses as they will get brittle, same with heater ducting.
Check your tyres are in good shape, and carry a spare main and n/w, or a repair kit.
a/frame and prop de-ice working?
If you can get hangarage, do so,even if its expensive; even so a fullset of a/c covers including engines,pitot,etc.
Remove batteries for any prolonged stop/overnight.
You may have to drain the oil if no hangarage and the temp. gets really down; then pre-heat the oil AND engine before you add warm oil.Make sure you know how to do it, and lock drain plugs etc, ---ALWAYS wear gloves as if you touch cold metal surfaces, you will leave your skin behind!!
Oleos may leak if cold soaked--- if you are really stuck top up with warm engine oil as it is thicker.
Take a couple of de-icing spray cans to de-ice around tyres as they can freeze to a wet/damp surface- failing that , pi** over them!
In-flight , exercise your props regularly at very cold temps as the CSU will get cold soaked an so will the oil.You may also need a partial- blanking plate for the oil coolers,even if they have flaps.
Survival-- sleeping bags, engie/a/f covers, PLB (2), mobile, first-aid kit , flares, food, good cold weather clothing, and wear it whilst flying , in case the heater may fail. FIRE-LIGHTING KIT ,.... the list is endless, but..., better to be prepared.
You may wish to think about speaking to Safety Services at Kemble, or Far North at Wick, for eqt, or cheap fuel if you went across from there.
As I said, others may have different thoughts, but hope it works ..
PS.. IT WILL TAKE YOU A LOT LONGER TO PREP THE A/C. AND CHECK DAYLIGHT HOURS FOR THE LATITUDE.Ensure you land well b4 daylight ends, and beware the windchill factor .... and...etc
