The actual weight you can tow is not as much as most people thought.
Towing capacity is towing capacity, no mystery there. It is a maximum amount of weight that can be towed while staying within the limits of other parts of the vehicle such as GCWR (Gross Combined Weight Rating) and GAWR (Gross Axle Weight Rating).
Lastly hitch (tongue) weight must be considered. Tongue weight is also specified by the manufacturer and if you happen to be over on tongue weight but below GCWR then you could adjust the load in the trailer and put more weight behind the axle.
