Here is my setup.
Overall, I love the switch n go. Being able to put the box on the ground for big removal days and fill it with my small tractor is also a huge plus.
After owning it for 6 months here is what I would have changed: I would have gotten a longer wheelbase truck, the rear tires are dead center on the chip box. I can make a u-turn just about anywhere, but when loading the box full of oak, the 3' of overhang behind the tires gave the box enough leverage to lift the front tire of the truck off the ground.
Changing the lift angle let me load with all 4 tires on the ground.
2. The bolt on roof collects water in the tubing somewhere and leaks down the front drivers side of the box, should be an easy fix but haven't had time yet.
3. The rear doors require some effort to latch in. Need to adjust the steel hing somehow.
4. There is a little play where the box rides on the truck, coming down hill and making a sharp turn the box will rock on the truck a few inches. Feels like you are tipping over for a second.
Again, great setup if you need to switch truck bodies or load from the ground. I would recommend getting the rear tires further toward the rear of the frame if you are picking up heavy loads.
