I have seen photos of a BOB (Yak) trailer attached to a Slipstream. I bought my Slipstream with a rear rack (Tubus Cargo). I'm wondering if there's any way to tell if the rear rack (and panniers) would interfere with attaching a BOB trailer. I realize that's a lot of space (and potential weight if used) being created for hauling and may be redundant but it would be nice to know just the same.

I have my eye on the Arkel Recumbant Panniers (the 60 model).
