I don't have any specific recommendation at this point, but we are working with Eaz Lift and a kit to work with the McHitch couplers, called the Quick Lift. We specialize in McHitch articulating couplers that are excellent for off road use, or for ease in connecting. McHitch.com.au. The Tremors use the 6 tonne automatic model and we sell a lot of them.
Equalizer is a brand I see a lot, but i'm not totally sold on them because the bars sit in a bracket that makes a lot of noise as it adds sway control. The sway control is not adjustable either. Blue Ox is another brand that a lot of people really like.
Go to etrailer and look for sway control devices. The telescoping units work well and are adjustable.
It's important to separate sway control from weight distribution. Two entirely separate functions. I don't like the idea of buying a WDH in order to get sway control and then not having it be adjustable. It just doesn't make sense.
I've been involved indirectly with Anderson hitches for about 5 years, as that is the brand used on Oliver trailers. They are used because they fit without cutting fiberglass, but there doesn't seem to be any other advantage. I have never liked them or the company. And they are especially bad for off-road, or rough road use.
Sorry I can't be more specific with a model at this point.
