I don't know where you live in Indiana but if you're not far from Montpelier, IN "Ickes" is the place to find about anything RV. They have multiple sizes of stainless steel sinks, faucets, etc. at reasonable prices. Phone # 765-728-5668, address 701 W Huntington St (State 18)
I have not financial interest in them but have been able to find many needed RV items.
