Sounds like a normal dealer.
All seriousness aside, unless your Jayco had the countertop extension stock or as an option, you will have to make your own by getting the hardware and making a matching top for the extension. Jayco may be willing to sell you a piece of matching counter material. If not, take a sample or a good picture of the counter top to a home center to see if they can match it up.
A kludge you might like would be to make the extension from a wooden cutting board. Besides having a convenient place to stash a cutting board, you wouldn't have to match the existing counter top.
