Yeah I'm not sure about harming the charger...all I can say is I've had it on for 2-3 days straight with nary a hiccup.
So remember when I said like 3 months ago that I'd have the cab off "this weekend"? Yeah, well that didn't happen...but it finally has. The removal mechanism involved a tree, which worked great. The procedure was quite a bit more complicated than it needed to be (lol), so I won't go into the details. Suffice it to say that I got the cab off, with a lot of help from my dad.
