I agree with Saabdoctor. Keystone's obligation for warranty is for the one year after purchase. The recall specifically outlines exactly what they will do. Anything they do after the warranty expires and/or extra above what the recall states they will do, is a "gesture of customer satisfaction" and not required. In the recall, there are specific instructions stating: "Continued use of the vehicle without replacing the transfer switch increases the risk of a fire, personal injury, and property damage."
You did not say when you purchased the Fuzion, but if it was after Feb 24, 2012, the dealer should have known about the recall and performed the work before he sold it to you (assuming you purchased it from a Keystone dealer and not from an individual or a "third party dealer".
In the case of the transfer switch, Keystone has met their "obligation" by performing the recall and exchanging the switch for one manufactured by another company. They have no obligation to do anything other than refer you to the manufacturer of the switch.
If you get no satisfaction from your dealer (assuming you purchased it from a Keystone dealer), and the manufacturer of the switch does not help, then you can (should) contact NHTSA. They may be able to intervene. You can contact them here:

Select FUZION and the recalls will be in the chart by subject. Open them to read exactly what the recall included.
You might want to review the other recalls in that chart to see if there are any others that might apply to your RV.
Good Luck
