What is the legal length that a camper can overhang a truck bed?

In the U.S., the legal length that a camper can overhang a truck bed varies by state and local regulations, but generally, the overhang should not exceed 3 to 4 feet beyond the rear bumper. Some states have specific guidelines regarding overall vehicle length, which typically should not exceed 65 to 75 feet for combined vehicles. It's essential to check state-specific laws and regulations to ensure compliance. Additionally, safety considerations should be taken into account, such as visibility for other drivers.
