Not according to my manual, which has a T fitting feeding air to both
tanks from the one vent on all models. It wouldn't be the first time
the
reality differed from the manuals, of course.

Must have changed at some point. Both of ours have the vent
feeding through a check valve into the LH tank, and a crossover vent
connection between the inboard walls of both tanks.
