Hello: I believe I've seen your comments and posts in Shanks' 208 forum. Funny I've been doing the exact same research. I've measured 32' center to center on the axels of the 208. and believe that the Cer 33 is the way to go. I've been to the MOR ryde website and found this. All the measurements you need to figure out which product you will need. If you haven't already done this step I hope it helps.

As my trailer is still in storage and about 45 min away I haven't been able to fill it out yet. I'm also gonna wait until my warranty runs out in mid summer before installing these babies. As you seem to be ahead in this project. I'd love to hear how it goes
Happy Camping.
