Yonder is an dialectical expression indicating a general direction to a destination or an object, generally but not required, to be within eyesight .
The expression comes from the archaic "yon". Does that help?
Hahaha, it's more specific than that IMO. It's something that isn't very close by but isn't very far away. Generally, it'll be more than 100 yards away and less than a mile. But scale matters, as well as the subject matter at hand, so the distances can change. This is also when being in eyesight can change it. Generally it has to be far enough to not be considered nearby, but close enough that you can see it.
Basically it's like saying "over there." There are two more words that can be used when an object is either close by (closer than yonder) or father away (than yonder), but I can't think of which two those are at the moment. Even better is that "over yonder" is apparently correct English even.
As far as my truck... apparently it doesn't like starting after spending a day and a half at -40 degrees. And that's even with it plugged in!
I ended up getting it going today, this was day three of trying to start it. Finally broke down and put one of those jet type heates under it... started up like a warm summer day after that.
