I'm beginning to think the old one was ductless and just used the two ducts as return air.
You're confused - as DrewE already described an RV air conditioner typically draws air in through the ceiling shroud, not cold air returns as does a home A/C. Those ducts you have and the fact your original A/C was controlled by a wall mounted thermostat says clearly it was a ducted system. What you've purchased is a direct blow system - a top unit plus the ceiling mounted ADB which blows air directly out vents and into the coach, no ducting involved. There's nothing wrong with this but you'd want to seal those two ducts you mentioned and of course the wall thermostat won't be used for controlling the A/C because the ADB itself has all the controls mounted on it. And as I already mentioned, you may perceive any direct blow system to be noisier than a ducted system because all the noise is concentrated in one area where the A/C is located.
