Leaving the power supply in the cab is a great idea. You could always warm up the cab with the trucks heater to get the power supply running.Doh!! I just looked and my Pecron s1500LFP has same -20c or -4f limit! I didn't expect it would cut off power though. Great tip! Maybe I should drive with power station in cab, then move to camper once parked, so I can get heater going! Thx for the tip, I have a trip to/from Denver this week, this could be a player!

Been there, done that. https://forum.expeditionportal.com/threads/ittogs-overlanding-trips.211456/post-2910085 Also on the pulling others out.A couple years ago I flipped my side-by side over in the woods and used the winch to pull it upright. You can even lift a deer into the bed, if you throw the line over a tree limb.
Lastly I end up pulling move vehicles out of ditches, than I actually pull my own truck out.
The only thing I am on the fence about is the Synthetic Line on my Warn. I like it because I don't cut up my hands on broken wires like on a steel line. The problem is that the synthetic rope gets stuck when spooled up easier. I would buy this again.
