Working in the parts dept for a Ford Heavy truck dealership I can give you one little tidbit of info...
Those Brazillian built motors are extremely difficult to look up parts for them. The are not well documented, and finding anything is a problem. When you buy a bus with US motor (Cummins, Caterpillar, Detroit) they are extremely well documented. Using the engine serial you can look up just about anything via the build sheets. However, there are no build sheets on the Brazillian motors, you just have to look up generic build lists to come up with part numbers.
You just might be a Redneck if...
...your motor home used to be a school bus!
...Your living room has a steering wheel!
...Your home has brake lights
