For those interested in the upgrade I just checked with Cummings last week. It's a 20 Week lead time for non OEM customers. They are pumping these out to the OEMs as fast as they can to meet manufacturer demand. You can find them on-line for about a grand more (if you want it quick) than you'll pay to wait.
I put my name on the order list to replace my Onan 2.5 KVD LP Genny which, interestingly enough, the control board failed on coming back from Jellystone last week. Just FYI if your Genny only runs when you have to hold the "start" button down you've had a control board failure. I intend to just drop mine from the camper to replace the board since trying to unscrew the four cover screws that seem to be torqued down by a gorrilla at the factory have been unsuccessful....but I digress.
From my research, here are some of the Part #s you'll need to make the swap:
Part Number Description
A063N9302.5HGLAA-8304
0155-2325Alum Steel TailpipeKit
0155-2449 Exhaust Resonator
0155-1015 Pipe Clamp
The LP input line is on the opposite side of the current model, same with the power. Additionally, the exhaust exits the Driver side vs the passenger side on the current model. Hence the additional Muffler and accessory tailpipe kit. I intend to install the resonator to see if it makes an additional reduction in Db without degrading Genny performance.
