"...For what it's worth, I had a trickle charger that was a solar fold
out leave on your dash, kind, at Grand Canyon. I ran my heater 24/7 and my
battery worked great. I was there for 3 day..."
I suspect that by the end of the 3 day, your
battery was quite drained. That is fine and what is supposed to
happen.
No matter what some of these solar trickle charger
companies say, if you say left your trailer for a month in the sun without using
it you would overcharge the battery. Not enough to kill it quickly, but it
will shorten the life of the battery.
