The Heartland website shows the 3055RL with a GVWR of 14,000 lbs and a dry weight of just over 11,000 lbs. A Reese 15K is suitable for the application by these numbers being rated at 15000 lbs. Some people prefer to add in a little 'cushion' with the hitch rating if possible. I believe hitch ratings include a 'safety factor' also, so they are safe at their rated capacity.
