You are talking about a vehicle that is above average weight. If it were my decision, I would go with the BlueOx Avail. This is a 10,000 Lb steel bar with extra length to allow for tighter turns. See attached link.
As for a braking system, there are many on the market and IMO, are all good. Some maybe better than others but they all have pros and cons. The BlueOx Patriot for instance requires zero modification to your vehicle and can be switched easily from one vehicle to another. The con is that it takes about two minutes to install and set up each time you hook up and you need to store the device when not in use.
I have not had experience with other braking systems but can say that I have about 20,000 miles with my BlueOx and have no complaints what so ever.
You will not go wrong with the BlueOx Product.
Regardless of what you pick, proper installation, care and use is "Critical"
