An OEM is going to be an AirEXCEL (Coleman) and if you want it ducted you will need a thermostat and if that wiring is not already in the wall that would be the problem Pull the trim ring at that roof vent and see if there is more than just the 110 wiring in the ceiling. If the thermo wires aren't there then you can only use a non-ducted unit unless you add wire mold across the ceiling and down the wall for the thermo.
It really doesn't make any difference as to what brand, the problem of ducted vs non ducted remains the same. If the dealer is not sure then you have problems.
