I had been worried about the fit of this ladder with my Vanspeed capsules but decided to give it a try. I installed them immediately behind my FVCO side steps and they do indeed fit. However, I was not able to install the (optional) support bracket included with the ladder. For the support bracket to work and connect to the frame, I would've needed to move the ladder back another 2" or so but the capsules prevented this. Otherwise, the install was easy and the ladder seems really stable without the bracket. Time will tell but as of now, two thumbs up.
