I have a question that's unrelated to yours but your picture sparked my mind on something I saw the other day. I know there are a few truckers on here so this is the perfect place to ask....
the other day I saw a tractor-trailer unit with great big fat wide tires on the trailer that look just like the ones above, but of course big trailer sized. I've never seen that before, always been the dually setup. Is that single wide tire common?
As for your truck, it's very purdy! If that's the underneath I can only imagine what the rest looks like!
