The cabinetry and other woodwork in RVs is typically made on shapers and that makes it very difficult to find off the shelf router bits that match the profile, even the shaper cutters the RV manufacturers use are almost impossible to find.
There are manufacturers in the US that make custom router bits, I have no experience with any of them, you have to do your own research.
You could also use multiple router bits to create the profile in stages, it can take some trial and error and funky jigs but is probably the quickest and cheapest way in a home shop.
