Hmm.. the wall is enough to raise an eyebrow on it own.
The first time I noticed the showers without the fiberglass surrounds were in Jayco's a couple of years ago at a show. I think it was the Jay Feather SLX line. Maybe the surround was optional as I know their water heaters are or used to be.
Evidently the vinyl paper covered luan plywood is waterproof enough. I am not sure if I would trust it long term if using the shower a lot, I'd add a surround or at least throw up some FRP around it. IMO the only purpose it serves is eliminating the cost of installing a $200 surround, sort of like installing entry doors that do not have windows. I always thought that was dumb and looked like hell. Maybe they could use the interior panels on the outside sidewall and roof if they're that waterproof?
