Ask Freigthliner or Cat they will tell you this is correct.
we have yet to find out who they had do it. It looks like our dime to correct it 3500.00

NO, it's not supposed to have a finned pan. There's a few zillion C-7s out there with steel pans on them. They CAN come with either one but, there's variable reasons for either. But, by far, about 99.999999% of the motorhomes out there with a C-7, have the steel pan.

Whaaaaaaaaaaaaaaat? "No baffling"???? "For a water pump"??????

Well, maybe you've not read the hundreds and hundreds of threads explaining WHY the C-7 CAN produce excessive oil mist from the blow-by tube. And it's NOT from "NO BAFFLING". The oil dip sticks were marked incorrectly and, unsuspecting owners would put too much oil in them, based on the style and type of oil pan. The STEEL pans are designed for a maximum of 19 quarts including the oil in the filter. The aluminum pans were calibrated for 22 quarts, including oil in the filter.

And, may I ask, what in the world does a WATER PUMP have to do with the oil pan? Nothing as far as I know.

With a bit of research, one can find numerous threads on folks that have re-marked their dip sticks, so they reflect the proper amount of oil to be installed after an oil change in their C-7.

I was referencing the Fleetwood Factory in South Carolina.
Also I saw the pan on our when we were having the oil changed in Decatur Indiana, after the Factory had fixed some items and before taking it back to Dealer, the biggest mistake in our lives to correct one of their mistakes and they wrecked it.
The 3126 is not the c the 3126 versions are topped out at 330 hp the C& is supposed to make 350 hp and 800 lbs of torque. The C7 superceeded the 3126 version, which also had a greasable fan bearing hub. Not sure of the year. Or maybe tehy replaced the entire engine with a 3126 as things do not look the same as original such as exhaust exit too low and when you would take of in the coach right after we bought it it would shoot out black exhaust and really scoot. The coach is lazy now.
