A 9,000 lb TT is a big trailer. Yes, a larger heavier truck will make it easier, as will an upper end expensive WDH. The larger truck will have noticeably stiffer springs, and much stiffer sidewall tires at 80 psi, which gets rid of a lot of towing squirm.
Many consider 7K TT, about the max for 1/2 ton towing.

I'm definitely in the 7,000# (7200#-7300#) camp max for a half ton. And even then, it needs to be the right half ton. My Payload exceeds 1500#. I often see posts where people are towing 7,000# with 1250# Payload. That doesn't leave much room for passengers and lunch.
