Recall Verification for Used RV

Does anyone know how you can verify if recalls were taken care of on a previously owned coach? We purchased a 2008 Winnebago Tour and were "told" by Camping World that all the recalls were addressed, but we know for certain that at least one of them was not! Since some of the recalls are quite serious, involving the steering components, we want to verify that the work had been performed. Doing a web search resulted in verification abilities for cars using the VIN number, but not RVs. Any help would be greatly appreciated!
