Engine serial numbers

[jamesmac]

I am having trouble finding the engine serial numbers on my 2004 monaco dynasty countess III can anyone help out.

When looking at the engine if it's a Cummins it should be on what's called a Data Plate on the timing gear housing on the same side as the fuel injection pump. Others have suggested it's listed on the build sheet that's usually located on the wall in a cabinet or closet inside the coach. Hope that helps.

Call Cummins with the Vin # and they will provide the engine serial number.
