Could be an error on their specification sheet.
If you look at the specs for Cedar Creek, the camper's GVWR minus the hitch weight = total axle weight. The 36RD5S for example...15635 - 1635 - 14000 (7000 lb axles). For the 38FL...15550 - 2550 = 13000 (6500 lb axles). This doesn't make sense? It seems that Cedar Creek uses either 6000 or 7000 lb axles for their floorplans with the exception of the 38FL. Perhaps the pin weight is incorrect and should be 1550 lbs.
Edit: The dry weight is 1247 lbs heavier on the 38FL than the 36RD5S and the GVWR are virtually the same.
