Gen prep is designed for an onan 5500. Which vents/exhausts/supply air all come from the bottom. That eliminates a vented access door and makes it quieter. If the person keeps the door closed, which it should be. So if the model fits the Onan 5500 footprint using the same mounting holes, you should be good. Might need an adapter for the remote start panel to connect to another brand.
