Tough river with trips

[Buck_65]

SB is 18/7.5/1.4 over 450 hands, which is my only read at the table.

Should I have raised SB's river donk bet? My read was that he made a flush here about 90% of the time here, he doesn't get out of line and doesn't bluff into multiple opponents. When it's 2 bets back to me, I can't possibly have the best hand, right?

Prefect. The initial river call is good. Once it's two back to you, your fold is fine. You're not good 1 in 9 times here.
