trailer load max out

So I have a Dodge dually Deisel 5.9 cummins has a max towable load of about 10000 lbs. But I see 3/4 ton trucks towing trailers I know are about 14000 lbs loaded. So is my truck's rating wrong ?

Those old trucks had some low tow ratings especially with the very weak auto tranny.
Now if your model truck has the 5 or 6 speed manual tranny then it will pull just about anything as long as the trailer hitch weight doesn't overload a tire/wheel/rear spring pack.
Lots of those trucks ran commercial service at over 26k gross combined back then.
