Battery Life and Low Temps
I have been having a ball up at Iris Meadow off of Rock Creek Road, Close to Mammoth Lakes, CA. It's the steeper side of the Sierras just East of Yosemite. It's a little known area comparably, but v...

jrnymn7,
Thanks for your long diatribe above ... however I'm not sure what the reason for it was.
Apparently you see no value in comparing long-time/low-current charging versus short-time/high-current charging, as you're convinced that the short and high scenario is the only way to go. BTW, I think that solar charging is long-time/low-current charging.
We don't camp much in restricted generator run-time CG's, so we use the equipment we have to the fullest when boondocking with no other campers around: The stock 13.8 volt RV converter - as is in so many other rigs besides ours - plus the small very quiet generator with one-half gallon of it's gas per charging cycle ... works well for us. AGM batteries with their low intrinsic impedance also help to make our system work for our hit and run traveling style (rock hounding in various remote non-campground places.) When we do have to camp in campgrounds with generator times, usually those times are at least two two-hour slots per day for a total of 4 hours. 4 hours is enough for us to bring up our batteries to 85-90 percent, which holds us between campsite moves - even in cold weather as the OP described.
Did you happen to open the link I gave for the (no longer avialable) 7455T Parallax charger? What do think of it's timed dual voltage output curve? I'm curious about it due to it's similarity to the system that Mex and others might be using where they pair-up, or supplement, a bulk voltage charger (~13.6 volts) with a manually timed and controlled higher voltage inexpensive charger to speed up the whole charging process. :h
