41, Tamiami Trail is 2 lanes, 1 each way for quite a ways. Running through Everglades National Park and Big Cypress National Preserve. It's not a bad road but it's not a freeway. At night, forget it. No lights and reduced speed limit due to wildlife, panthers, on the road. There are sensors along the road that detect when wildlife is on the road. Signs flash to warn drivers and the speed limit is reduced. As I said, not a bad road but don't know if you want to cross the state in a motorhome, pulling a trailer on it and definitely not at night. I-75 across is a better option.
