How can you assume that it's low compression, if his truck was running fine during warm temps but doesn't in the cold then is most likely not a compression problem?
How about some of these:
-Low/Old Batteries causing slow cranking speed, which will cause low combustion temperatures for firing fuel
-Gelled Fuel (he's talking about -34 degrees)
-Bad GPR or GP
-Oil does flow very well at -34 degrees to fire a HEUI system, even if he is using a lesser weight
-The list goes on
I would rule out the simple stuff before I started to look at compression
When is the last time you heard someone talking about loosing compression on a PSD, that's what they are built for, to make compression, has you seen the compression rings on these things? Plenty of 7.3 going around with 200,300 even above 500k with little to no loss of compression.
