The conversions are popular with the 4 wheel drive guys. My cousin who has a couple of Jeep dealerships has a younger brother who works with the 4 wheelers. They use them, but I think it is mostly to keep the dirt out rather than to keep the oil in. We also have a Diesel mechanic here who puts Cummins Diesels into Jeeps and he uses them. I have never heard of one being installed in a GM truck.
