I stay within factory tow ratings to stay legal. If you are overloaded and cause an accident you open yourself up to all kinds of legal problems...especially if someone is injured or killed.
Factory tow ratings have absolutely nothing to do with the law. The law is only concerned with GVW. As long as the tow rig is under GVW, and the trailer is under GVW (and you have the proper safety equipment) there is no way you can get a ticket.
Factory tow ratings are NOT legal limits. They are bean-counter recommendations based on not having to pay warranty repairs. Period. 1 year as an engineer for Ford and Volvo, and 4 years as a consultant for GM, Saab, Honda, Volvo, Nissan, and Mazda, along with a 16-year career CDL driver have taught me that.
If you get pulled over for a ticket, the only thing that is legally enforcable is the GVW of the vehicle and the GVW of the trailer. Those are the only registered legal capacities that they have access to. They don't have a book that says "an F150 extended cab 4x4 with the 4.6L and 3.45 gears (with optional transmission cooler and tow package) can tow 5900 lbs." Even if they had that magic book that listed all the tow ratings for every possible combination of tow vehicle, how many of them will crawl under the car to decode the axle tag, look for 4x4, be able to establish if it has the transmission cooler and tow package, measure the wheelbase, verify tire load rating.... the list is endless. The law allows them (unfortunately) to discern for themselves what "appears" to be safe and what isn't. I used to be a full-time RVer. I towed a 31' travel trailer with an F250 diesel. At one point in Montana, my weight distribution bars were stolen, so I had to drive 150 miles with my tail sagging. I got two tickets in that 150 miles for "unsafe towing."
