same sink without the drain board that may be workable in trailers with less counter space.
Delta 101 DST faucet had 1/4" lines terminated in 3/8" compression fittings. After a visit to my favorite ACE Hardware, I came home with a couple Watts valves that had 1/2" PEX inlets and 1/4" PEX outlets to make the connection. Easiest bit of plumbing I've ever done. Just cut the lines square and push them into the shark-bite style valves until they're fully seated.
