We have a company in Aus called Hayman Reese who do a 2inch kit. When I worked for the factory they were under the impression Americans use pick up trucks to tow with but Australian culture was a sedan doing all of the duties (6cyl Ford Falcon and Holden Commodore) hence both of them have 2000kg tow rating. We had issues when the Hybrid Camry launched with no tow rating and it stopped a lot of consumers buying it. Australia ended up given the new generation Camry 500kg where as far as I know no-where else in the world had any rating.
