Gooseneck trailers are way more stable pulling loads than bumper pulls. All states have different laws when it comes to towing and no two law officers or dot officers in the same state will give you the same answer. Some states like Missouri anything towing with a trailer gross weight over 10000 has to scale and other states anything over 26000. Only towing considered exempt is recreational like campers. The gooseneck utility trailer I have left I bought when I had a 2010 3500 dodge. Tow capacity of that truck was some where over 14000. Truck weighed about 8600, trailer gross weight was 14000 rating. I was legal to tow it without having to stop at most state scales. Not Missouri. Sold the 2010 dodge and now own a 2002 3500 dodge, Tow capacity is a smig over 10000. So not legal to pull the goose neck according to dot laws. According to dot it doesn't matter if you have a push mower on the trailer rated at 14000 gw. Your not over weight but they go by the rated weight not actual weight. Farmers in most states are exempt when doing farm related towing as long as your not making money. Meaning someone else is paying you to move their tractor or haul their hay. At that point your commercial and then it's a hole different set of rules. Lots of laws and they get tangled and miss interpreted and do I still tow my goose neck. Yep but only for my needs. Am I breaking the law. Probably. If I bought another gooseneck to be towed behind a pickup I would get one with 7 to 8 thousand lbs axles and have it tagged at 9999 lbs gw. If you get a big deck over rated at 20000' truck is rated over that weight to tow and you plan on making money using the rig better check into licenses, dot numbers, insurance the whole ball of wax. You may get by for years towing not having proper stuff but just one little bump or cut a corner to sharp and scrape a fender any little thing and have police involved and dot shows up it turns out to be a bad day. I myself have never meet a dot official that didn't say awh just go on. They like to pick, pick, pick and write and write. The new dodges 3500's and ford f350's I think are rated over tow capacities of 26000. Now according to dot regs because it's rated at over 26000 you have to have a commercial licenses. Even though you just haul the weekly groceries home from krogers or where ever.
