In my area most dualy trailers have 2-10,000 lb. axles and the tri-axles have 3-7,000 lb axles. Trailers are usually rated by adding the axle capacities and the coupler capacity to get the total capacity. So if it has 2-10,000 axles and a 6,000lb gooseneck couple it would be rated at 26,000 lbs. Then you have to subtract the weight of the trailer to get the available payload. The difference between the 2 is that the tri-axle will be cheaper for several reasons, mainly because since the axles are spaced farther apart from front to back and cover a larger frame section they usually have a lighter frame. They also have 2 less tires and the total cost for 3 axles is less than for 2-10.000's. The disadvantage for tri-axles is they have 2 less tires to carry the same load and they have less square inches of brakes. They are also a lot harder on tires due to the inherent alignment issues with trailer axles. If you can afford it a tandem dualy is a much better deal than a tri-axle setup.

My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
