Interesting. I just created this account and this was going to be my first question.
I'm only going away for three months though. I'm probably going to leave it outside.... Will look into climate controlled units but I'm not sure it's worth it for only three months.
Look forward to reading through all the comments.
Just starting to read through the entire thread now.
The battery is more of less new. I just bought the truck back in September.
I didn't realize flat spots can develop that quickly.
