Recommend boarding the ferry at Los Ebanos from the Texas side as the Mexican side gets deeply rutted and slick. The Texas side is rocky dirt that seems better maintained making it easier to ride onto the ferry. Especially on 900lb Harleys.
I wouldn't spend any time sight-seeing around Ciudad Gustavo Diaz Ordiz, either.
