The dually Stable Lift has wider plates under the side wings. If it was not built with the wider plates, you will have to do some welding to extend the width.
The dually stable lift accomplish the extra room needed up front for the dually is accomplished by simply making the lift wider. It also uses a wider steel plate under each side wing, which sticks out the side of most TCs about four inches. The "hoop" at the bottom uses a wider spacing from side to side.
I really can't see how you could improve the quality of the Lift. You could modify the design to better suit a given TC, but it really would be minor. The three stabilizers look pretty sleazy, but they do their job. when installed. The box that the three switches are mounted in also looks pretty tacky. I painted my blue plastic electrical box black, and it looks much better.
I replaced my four hydraulic jacks with the Stable Lift in about 2005. It has never given me any problem at all. I have used my TC off the truck on some exceptionally uneven ground. With the stabilizers in place, the TC feels like it is in a foundation.
My truck is a 2WD, so it sits lower than a 4WD. Some folks think they loose too much ground clearance with the lift. If the lift is mounted properly, you only loose about 2 to 2-1/2 inches. I have never found that to be an issue. I do not use my TC for offroad excursions, I use my Samurai for that.
I installed my lift by myself, in one day, and I was 61 years old at the time. I have taken the jacks apart to see what was inside, and simply stated they are trailer jacks, made by a major company. They have provisions to raise or lower the jacks if there is a problem with a motor.
With help from a friend, we made a wired remote. I can walk around the TC and see what is happening when raising or lowering.
My lift cost me about $2500. It is definitely stable, loading in high wind is not an issue, and very solid off the truck. You can use the lift off the truck without the three stabilizers, but you may get some side sway as you do with four jacks.

During the install.

Ground clearance reduced by the Diameter of the tubing.

On a duelly, the plate under the sides would be wider, and stick out past the sides of the TC. This moves the jacks and tubing away from the body for more clearance.
