Hitch install question

Question about hitch etc installation:
The dealer where I bought my TM installed my hitch etc on my then to be TV.
Did a great job,but not cheap and farther away.
I now have a new TV and called one of the larger local U-Haul places that installs hitches etc.
Much cheaper and they seem to know what they are doing.
Any thoughts on using a travel trailer dealer vs a U-Haul place?
Also as I understand it there are only two hitch manufacturers in the US-Reese and Curt. They both seem to make good hitches. So either one would work?
Finally, I understand I have to get a new hitch for the new TV, but since my receiver hitch looks to be adjustable I should be able to use it and my wdh bars. Only have to get new wiring harness and then can use original brake controller that is only about 3 years old?
Any thoughts?
