Hey Eric! Yes, the Cummins Onan Quiet Series Onboard RV Generator - 4,000 Watts - Gasoline # CM32ZR is the correct replacement for the generator in your motorhome. This will fit in the same spot as your existing QG 4000.
What happened to your old generator?

Thanks! Old one just gave out, right after the warranty was up too. Oh well, these things happen. I've had them in the past without any issues so I'm sure this time around I'll have better luck.
