I did find one RV manufactures using carriage bolts recessed into the floor, then the wall structure placed over them. In another case (Arctic Fox) used a steel fastener (similar to a washer) used with the bolt-head.
It might take a call to Jayco to confirm what is going on top-side...: 574-825-5861 (have your VIN handy).
