Question about this, I suppose its probably too much work to have haulers turn corners? I guess the only way to do it is like, have each hauler segment be its own token which would be a lot. (the way the game handles hauler movement is vague but the existence of skitch hook implies that haulers can sometimes become <<bent>> so I presume they do turn like snake rather than move as one monolith like this tool seems to do)
I think the idea is that you can skitch around the end of a hauler ending up in the space just past it (when it’s no longer adjacent), essentially giving you at least 2 extra squares of movement. I say at least because there’s also the possibility that the haulers are lined up in a way that would let you chain across multiple haulers that way. Does that make sense? I don’t think they’re ever meant to bend.

I think its very vague about how this works so you could be right but it seems to me like haulers are not monolithic and can bend as the skitch hook rule also states that you <<continue along its side>> which to me implies that there is more than one space to continue along. Or perhaps skitch hook is trying to say you can start the skitch from one of the ends?
Ultimately this is kind of open to interpretation.
