You will be fine. I think I know the unit are getting. I looked at it up in Coppell. I had a trailer I needed to trade in so I went new. As far as the hitch goes you will be fine with that one. It wont transfer as much weight to the front of the truck as a heavier hitch but with that truck it will be fine.
Congratulations you will love it! hopefully the ice will clear up soon. I live just south of Dallas and I think everything is closed down. Big Daddy and Colem sent that cold stuff down here since I was bragging about the TX weather!
