Funny enough... I drove our Forest River Class C through 6 of these areas.
We Just got a 2015 Jayco Precept 31UL 3 weeks ago and I would never take this rig through a few of the same ones again. Highway 1 in California is fine. St. Louis was correct though. Someone busted out our locks and started to get inside but the dogs scared them off. They didn't get anything. Chicago sucked. Downtown San Francisco was a nightmare. Won't do that again. Had no issues in Death Valley in the summer. Drove slow though and kept generator on with AC. Yellowstone was pretty difficult to find parking since we don't have a tow vehicle.
