Be aware, that motorized RV's use a different lock than trailers do.
Motorized RV's have the deadbolt on TOP, above the striker, while trailers have the deadbolt on the bottom, BELOW the striker.
That being said, there is one competitor that I know of for electronic locks for RV's which is
Bauer EM Bluetooth | Bauer Products this is the Bauer EM, and the model NE, both the bluetooth and not bluetooth versions, are designed for trailers.
RVLock is much clearer on this, as they have examples of various handles and tell you which of their locks is the correct lock to match up with it. Once you start using an electronic lock, you will wonder how you ever got along without it. I first installed a Schlage electronic lock on my workshop years ago to get a key off my keyring. Later I bought another one for the house and that allowed me to pare off another key. RV's are a PITA anyhow with the number of keys you need to get into various doors. You will wish you had bought the electronic lock years ago. No wagging keys around when you go for a hike on a trail or even just to wander off to the campground restrooms or showers.
I would have thought that WBO would have installed an electric lock on the coach door. My 2007 View had one and it was tied to the circuit for the cab RH door lock/unlock circuit, so that when you used the fob to lock or unlock the cab doors the coach door was also locked or unlocked.
