I used to tow a 4000 lbs bass boat behind a 3/4 ton Dodge and I never knew it was back there. Later, I sold the Dodge and went to a very capable F-150. It towed the boat fine but I definitely knew it was back there. I could feel it as I drove and especially when I came to a stop. I then traded that truck in for a 3/4 F-250 and again I tow that boat without knowing its back there. Now imagine three times the weight and how much the difference in towing will be.
Although the 1/2 ton can do the job, the 3/4 ton is just built to tow. It's much more capable, stable, and safer.
