Brett makes as excellent point with this example. Many diesel coach owners are not aware of the coolant requirements on many (not all) Diesel engines. Many are unaware of the air dryer and its maintenance. Many are under the impression that the transmission needs no attention.
Here is a fairly complete list of possible maintenance points on a diesel coach:
Complete base line service for Cummins diesel motorhome:
Engine: filters to be Fleetguard
2. Fuel filters (2)
3. Coolant filter if equipped and test/ adjust SCA level if standard coolant. Change coolant @ 5 years. Add extender at 3 years if OAT type coolant.
4. Air filter if over 3 years old. Inspect plumbing between filter and turbo inlet for evidence of dust. Inspect CAC plumbing.
5. Inspect hoses & belts.
Transmission: filters to be Allison high capacity.
1. Change filters @ 36 months & top up.
2. Change fluid @ 48 months or test sample.
