One of the first items we changed when we got 5vr..kitchen sink and bathroom sink faucets from the cheapo RV ones to quality residential ones.
The back of sink base measurement (area faucet sits on) is important.
Also the size of water supply connections/fittings.
Ours was a straight replacement.
Wish I could have found a residential shower faucet with the shower head hose connection. That one is still RV junk (plastic)and replaced once due to cracked plastic internal 'T'
Access and mounting space limits what I could do.
