I'm posting this here for posterity in case others have the issues I've had finding this part. The latch on one of the basement compartment door on my 2015 Precept is broken and I've had a heck of a time identifying the part number and even more, a vendor. So here's what I've come up with:
Jayco part 0212767 that Jayco says is made by Nova. But Challenger makes the door and apparently that locking latch with part number 636000. I finally found more info on it at the Dutchmen owners group forum.
You can apparently order via Challenger inside sales but I've also found this link and they will key it to match your previous keys:
