[Former StClairSailor]

With the dealer, measured the height of our 310RET before pulling off the lot. Spec states 12' 9". I measured 12' 9" at the top of the a/c cover. That number was written down and affixed to the windshield. Even when not towing, I find myself watching bridge heights. Purchased Allstays app recently but still trying to make it work.
