thanks for taking the time to review the FSDs. my coach came with bilsteins and I had no complaints, but after hearing all the hoop-la about the koni fsd, I did what you did (about 3 months ago).
Not a day and night difference (as the bilsteins are very good) but an overall better shock for all around driving.
I have not yet been on an extended drive so my opinion is only based on 6 hours of driving, 3 on the freeway and 3 on mountain roads.
