Consensus is Proprop is best if you have mad cash. But a good Blue Ox or other quality no sway WDH should work well for your application. I'm constantly swapping trailers so I use the Andersen no sway WDH. Even it would work well for that size trailer & a half ton truck.

You will get the most out of your hitch if you set it up on a tripple scale such as a truck stop CAT scale. Normal truck wheelbase, If you can keep 85 percent or greater of your rear axle weight on your front axles you will have a safe stable truck & trailer.

I ran into an interesting post on another forum. If you want / need to reduce your tongue weight, consider getting either a ProPride or Hensley hitch. Using either will reduce your tongue weight significantly more than what the hitch itself adds.
Because of the design of these hitches, they make the front to back measurement longer - moving the trailer back from the truck. This increases the mechanical advantage lowering the weight on the truck and increasing weight on the trailer axle(s). You see this in the method posted in numerous places on how to weigh the tongue using a bathroom scale.
Confirming this is information on a site selling power tow dollies. "since our dollies generally attach further underneath most trailers, more weight is put onto them, giving you even more critical traction" http://www.powerdolly.co/critical-factors. Conversely, moving the hitch point farther forward reduces the weight.

An added benefit - moving the trailer away from the truck will make it more likely that you can open the tailgate while hooked up, which seems to be an issue for many.

I had a similar trailer (less hitch weight because of it axle placement) and was able to run my 2010 with a basic WDH. When I traded up to a 2016 I should have gotten a new WDH with sway control. This problem got a lot worse when we bought a new (1000lb heavier) trailer with a hitch weight close to your 780lb. We upgraded the bars to accommodate the extra weight but it wasn't a weight distribution problem (the truck is level) so I think you would be wasting money getting 1200lb bars.

I am going to buy the Anderson WDH in a month. Its less expensive and a lot lighter and quieter. I was a bit concerned about the weight distribution (what some people complain about) but I watch "The Fast Lane Truck" and saw the video where they did their "Ike Gauntlet" challenge with my truck and with the Anderson they had no trouble leveling it with their 900/9000lb test trailer. (Their trailer expert is a fan of the Anderson for its ease of setup, why they use it for their truck towing tests). Full disclosure: I am buying it from a retailer with a no-questions-asked return policy so if I don't like how it levels/tows I can take it back.

Thanks for the advise about he Anderson. Hadn't considered that one.

If you consider buying online from the largest online retailer, the husky centerline is around 300.00. Which is about 200.00 less than the Anderson. Of course you'd have to do your own setup.

I watch TFL trucks also. It's amazing the beating they put on a truck towing the Ike gauntlet.

I use an Equal-I-zer and love it for my 7k lb trailer. Worlds better than my old spring bar WDH with the chain links and separate sway bar.
