Rear AC unit & air from front vents

[GoneFishin]

We have 2 roof mounted air conditioner units, one in the front galley area and one in the rear bedroom. (A configuration I'm sure everyone is familiar with.)

When the rear AC is on in the bedroom (and the dump vent is closed), the air is directed out the ceiling vents. Does anyone get air out of the front vents?

We get some air out the front street side vents, but not the curb side vents. We're not sure if any air is supposed to come out in the front from the rear AC unit.

The dealer techs told us with the rear AC on, the front vents on the street side should provide cold air and the galley side vents are the in-take vents. Does this make sense?

Trying to understand from your experience, not what the dealer is trying to sweep under the rug. Sorry if this isn't clear, it's late. Thanks!

Ours is the same, just checked it to be sure.

I always thought that the return air was built into the grills attached to the AC units. That is the filtered air returning into the AC unit itself. The ceiling vents are strictly supply, not return.

I believe it has more to do with the fan output into the vent manifold. I have always noticed a difference in air pressure at the vents on the right side versus the left side.
