Distance between wheels very close?? Cedar Creek

Looking at the photo, while it's difficult to tell for sure, the rear tire appears to be forward of the centerline of the skirt cutout, which would suggest that axle is too far forward. If it turns out to be okay, I can tell you my signature FW does not have much clearance between the tires (although more than yours) and I was unable to use my BAL x-chocks and went with One-Step chocks instead.
