I have had the Bils on my '08. Very good shock for running empty or moderately loaded. They have been replaced by Rancho 9000s. The adjust ability of the Ranchos makes them the better choice when I hook onto the toy hauler. The Bils just did not have the control I wanted with the heavy 5er. I did like that they had more rebound damping compared to the compression side. Other manufacturers should learn from that.
