I did some research before buying the Airstream about what kind of hitch to use to drag it around the country. Since I have only ever towed trailers that I can push around with my hands, the 7000 lb beast is a big change. With an 800 lb tongue weight, it is also 300 lbs more than what my class 3 hitch is rated for. Bad news right? Well, that’s where the weight distribution systems come in. By using a weight distributing system, my class 3 hitch can increase its capacity to accommodate up to 1000 lbs of tongue weight and 10,000 lbs of trailer weight. Magic!
These hitches essentially use leverage created by solid metal bars that extend from the rear of the hitch to even the weight across all 4 wheels of the vehicle. There are people who will go on and on about how these work but I like to think of it as a wheel barrel. The handles of the wheel barrel are the metal bars and it takes the weight off of the back and moves it to the front. If you want to find out more, do some searches on the wide wide world of web. There are people who will tell you a lot more about it than I am willing to bore you to tears with.
