Bought new TT today, 2016 Stealth, worried I cant pull it!

I once was in your shoes. I did pull all over the place but I was not happy with the truck's performance. I was always adding stuff to make it tow better. a friend of mine told me I should have bought a 3/4 ton. my son was in a wreck,(minor), and I used that as an excuse to update truck to a 3/4 ton, boy was my friend right, 3/4 ton ran circles around the 1/2 ton. I just wish he would have told me sooner.
