Have driven my van through several winters in Minnesota and Wisconsin.  A
little seam rust but no real problem.

Have had a problem with short trips in the cold.  The oil dilutes with gas
really quickly.  Sometimes in just a tank or two if you only drive 1-2 miles
at a time.  Just change the oil very frequently or park the van.  Of course
I was only using a tank of gas every month and a half or so.

Synthetic lube in the trans will help lots come 30 below weather.

Do you have a BA-6?  Not much heat from the regular heater at below zero.
Buy some warm clothes!

St. Cloud is down south from here but a very nice place for most folks.
Near Lake Woe Be Gone also.
