South-central PA here, we woke up one late October Saturday a few years back to 6" of snow. My trailer isn't optimized for cold, but temps hovered around 32 all day so I wasn't too concerned. We did go through some propane. We left Saturday afternoon only because the campground lost power and then lost water pressure. Kids had a blast of course.
Check your forecast that week. If temps go below freezing only overnight then I would go for it. We're headed out for the last trip of the year this weekend. It may dip down to freezing Saturday night. I would consider wrapping exposed water lines if temps dropped into the low 20's for an extended period.
