Back in January buddy and I were going to camp in and ride from the trailer... got to the mountain around 2200 and fired up the generator, but the propane was liquefying in the line before it got to the furnace, and I think the regulator was freezing up. Camped out at the hotel in town that week, temps got down to -55°F at night. Fucking frigid cold.
Diesels were all gelled (even the ones with winter blend) and half the gassers in the lot didn't want to start.
Happens at 10k ft in January.
