Would it be safe to pull a 35ft 5th wheel on UT-12?

Nah, the first time we did it was because of a gps shortest route misdirection and we were pulling a TT. We were a bit surprised of course but had no problems. Of course the TT was a 20 ft popup and we were driving a 'Burb. And being from Florida we are the prototypical flatlanders. It's all in your head.
