Question:
Wondering why Im not seeing the Onan P5000iDF EFI generator on your site?? I live in the Western US and fuel injection is more than a nice to have at altitude.

Thanks for reaching out Frederick. Like you mentioned, we unfortunately don't carry the Onan P5000iDF EFI generator just yet. The Onan 9,500-Watt Dual Fuel Portable Generator # CM38MR is currently the only portable generator we offer with electronic fuel injection (EFI). It's obviously a much larger generator than the P5000iDF.
The closest option we currently carry in terms of features and output is the Onan 4,500-Watt Dual Fuel Portable Inverter Generator # CM86MR. While this model is carbureted rather than fuel injected, it can be paired with the Cummins High Altitude Carburetor Kit # CM46GR. This kit includes three different carburetor jets that allow you to properly configure the generator for operation at elevations up to 7,000 feet.
Are you usually camping or staying at one consistent elevation?
