I agree, the 2007 & up Jeep JK Wrangler tow capacity is 2000lbs for the 2dr and 3500lbs for the 4dr. Both have the same engine and drivetrain. The 4dr is heavier, but is longer so it tows 75% more weight!
Unless you are in Europe, then the same 4 door JK can tow 2000 kilograms or 4,409.24524 pounds.
