Its not a camshaft issue its a hydraulic lifter issue, which then takes out the camshaftCounterpoint: most modern gassers seem to have an unhealthy appetite for eating camshafts...
Gas on their own are the way to go for cold. Two years ago I was pushing snow on a -25*F day with a 1953 gas tractor. Both Bronco and F-150 started and moved out of their spots in the driveway so I could clear it and the carbureted Ranger even woke up after a two week nap to pull the Bronco out of a snowdrift.
It was afunmemorable day.

Or its an oiling issue (often from the variable displacement system) that starves the lifters from proper lubrication.
However you want to dice it the camshafts suffer greatly. And they used to last forever, especially with roller lifters.
