Factor #2: You Might Break the Law
In the US, each individual state has its own laws regarding towing and equipment. You can find the long list of Arizona laws here (this excludes local laws). Some of these laws are common sense. Like the one that says: If a vehicle is towing another vehicle and the connection consists of a chain, rope or cable, a white flag or cloth at least twelve inches square shall be displayed on the connection. Others are confusing, such as the law that states that:
“A resident shall not operate, move or leave standing on a highway a motor vehicle, trailer or semitrailer that is: Owned by a nonresident and that is primarily under the control of a resident of this state for more than seven months unless the motor vehicle, trailer or semitrailer has been registered with the department for the current registration year.”
Read that twice. In general, where legalities are concerned, it’s best to leave it to the professionals. Otherwise you might end up costing yourself way more money than what the original tow would have cost in the first place.
