I found that the mv90 turned out to be a good choice for my application. I have a small ARB compressor mounted to run just the lockers and when I go to an event like GoneMoab, or WentWindrock I air down at the beginning of the week and stay there for the week. The 90 puts out a lot more air than...
Picked up a 12v electric blanket a few years ago, it has a built in timer so you don't have to think about turning it off. Just put inside the sleeping bag, when the cold wakes you up turn it on, and go back to sleep. has never drained the battery enough to worry about it.
