I put a full Banks system on, so no more problems. I like the low RPM torque compared to the V10 Fords. Mileage is about the same, but as I have always said, "If you are worried about fuel mileage, stay home"
Happy Glamping.

One of the leading causes for cracked exhaust manifold/s (if not the leading cause)...quick shutdown after grade pull and/or long highway run. I always allow the engine to run for 3-5 mins prior to shutdown if I pull off the highway and/or exit after a grade pull.
