Dual a/c operation

Is this normal? When I'm running main a/c and not the bedroom a/c, I can feel cold air coming out of bedroom a/c return air vent, thru the filter. Surely that can't be normal as any dust captured in the filter is blown out onto the bed.

Somewhat normal, yes. Think of it this way. Common duct system between the 2 AC's. Rear AC running, air goes through the duct, into the discharge ducting of the front AC, through the cage fan, through the coils and out the intake. Nothing really to stop the air from going that way, unless front is on as well. Shouldn't be any huge amount of air, but a little no doubt will make it through there.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.
