Fifth wheels are a popular RV type known for their distinctive design, raised forward section above the truck bed, and spacious and comfortable living areas. This type of RV is the largest towable, ranging from 22 to 45 feet long and weighing 7,000 to 20,000 pounds. Fifth wheels are best suited for extended trips, family vacations, or full-time living, as they offer plenty of space for several occupants and numerous amenities. To tow a fifth wheel, you will need a heavy-duty truck equipped with a specialized hitch mounted in the truck's bed. You will also need experience handling larger trailers, especially when navigating tight turns and backing up.
