As much as I agree with your logic, I have to disagree at the same time. I bought an aftermarket suspension for my Commander and still had to put many hours and more money into it to make it work. I am not the only one with this experience. It is also not just one manufacture. So it's a double edged sword. You spend a lot of time and money making your one more than once to get it right or spend big bucks to buy something and have to modify it to make it right! Don't shoot the messenger just sharing mine a few others experience's.
