You sure are due for a new one. In fact, I would go the whole way and replace not only the hitch head, but the WD set up AND anti sway as well.
Reese Dual Cam or Equal-I-Zer....about 50/50 choice. I prefer the EQ, others love the Reese. For something as inportant as this, don't mess around with just replacing the head, as you will need new weight bars to go with your new TV as well. It's a HUGE
difference between the Olds and a 1-ton truck!!!
Any quality trailer shop should have them and can properly install it as well, or Camping World as a last resort!
