Went to my local Chevrolet dealer yesterday to have the oil/filter changed.
$59.00 for a Full Synthetic Oil change with filter (AC Dexos 1 or Mobil 1, 6 Quarts) I use Mobil 1. Did not feel like changing the oil myself.
While the RT was being serviced i asked my service tech some questions about the engine/transmission/rear end. Next thing i know he hands me a 6 page printout( Build Sheet) of my Express 3500. Everything i ever wanted to know is on those sheets. Read it and placed it in my service records for future reference.
So if you own a Chevrolet base RV and want to know what it has in detail
take your vehicle registration that has the VIN number on it to your Chevrolet dealer and have them print you out a copy.
I would imagine that Dodge, MB, Ford would do the same.
