There is only one recall that I am aware of. I purchased mine new and was notified. Recall done in Florida at chassis dealer. Following is from HR 419 Pushers group. Just check the build timeframes and the numbers given. If your unit falls into group, recall should be done, by dealer or at a Roadmaster authorized shop.
