Since you will never tow a dry trailer, please assume the maximum load. So, 7000 pound trailer plus hitch comes up to the 980 or so pounds you list. The same applies to your TV. What does it weigh loaded ready to travel with your family on board? It certainally will not be the advertised curb weight. It will be somewhere in between the two. To error on the side of caution always, always use worst case scenario. Your wallet will thank you. Like someone else mentioned, your family will not be the same weight next year or the year after. So plan for 5 yeaes down the road.
