I think i read it right--8000lbs with the trailer and tractor weight. Your truck should be able to handle 8000# comfortably. Road design can make be a factor in how well it pulls. One differance in curves is whether the curve is banked or the not. A flat curve would make the trailer not track as straight and build up some momentum to push the rear of the truck towards the outside of the curve. A race track is a good example. On a banked curve track they can corner at a higher speed, try the same speed on a flat corner and the rear wheels will lost traction and start to come around and spin out the car.

Your right a dual wheel is a little harder to push around. There's no substitue for getting to know how your truck reacts in certain road conditions and adjusting your speed to them. It maybe that a dually would perform better for your setup and road conditions. First, You could try moving the tractor rearward and try to get 60% on the trailer and 40% on the truck and see if its better. Just fine tuning the load for the best ride. There is a point where you can have too much weight on the hitch effecting the ride, just as there can be too much weight on the trailer tail. The sway and fishtail happen when theres too much weight rearward and it's easy to tell when you have reached that point.
The alternative to dual wheels is to improve your equipment to reduce the push with the weight distributing hitches with sway bars and also the friction sway controls that mount on a small ball on your receiver block and trailer frame. Either way there are advantages and disadvantages and both approaches have higher costs. Tire, brake and repair costs are higher on duallys. My neighbor complains about poor tread life on his. Plus the wheels are too big for the average tire balancer to have the right adapter. So he ends up looking for places that have the right wheel balancer to buy his tires.

Trailer design comment, i have seen people make trailers with mobile home axles and no springs. They really ride rough and will really push on a truck even when empty.
