Replace vanity faucet/diverter with single handle/diverter?

You might look at the Scandvik 460xx part numbers which are combination faucets and pull out showers, or the 144xx which are single lever control versions. My camper had separate shower plumbing so I used the 10500 shower mixer which is quite compact, and a bulkhead fitting to connect the shower handset. I posted a bunch of pictures on the job, but the whole thread seems to be missing now.
