Finding a comprehensive service manual specifically for a 1978 Dodge Commander motorhome can be challenging. These vehicles, while iconic, are relatively rare, and original documentation is often difficult to locate. This guide will provide strategies for locating service information and offer insights into maintaining your classic motorhome.
Where to Find a 1978 Dodge Commander Motorhome Service Manual?
Unfortunately, a dedicated, single-source service manual for the 1978 Dodge Commander motorhome is unlikely to exist readily available online or in physical form. The complexity lies in the fact that these vehicles were essentially custom builds, combining a Dodge chassis with a separately manufactured coach body. This means the service needs are a blend of automotive and RV-specific requirements.
Here's a breakdown of your best approaches:
1. Focusing on Component Manuals: Instead of seeking a single all-encompassing manual, consider gathering information piecemeal. Your approach should be focused on the individual components:
-
Dodge Chassis Manual: Identify the specific Dodge chassis (e.g., the engine type and model—a 318 or 440 Chrysler V8 was common) to locate a suitable repair manual. These can often be found through online retailers selling automotive repair manuals like Haynes or Chilton. These manuals will cover the engine, transmission, brakes, steering, and other chassis-related systems.
-
RV Systems Manuals: The living quarters of your motorhome contain numerous systems needing separate attention. These will require separate manuals focusing on:
- Plumbing System: Find manuals relating to your specific water pump, water heater, and plumbing fixtures.
- Electrical System: Locate information for your specific wiring, power converter, and appliances.
- HVAC System: Get a manual covering your air conditioning and heating systems.
- Appliance Manuals: Consult the manuals for your refrigerator, stove, and other appliances, as these are often from different manufacturers and require separate servicing.
2. Online Forums and Communities: Join online forums and communities dedicated to vintage RVs, Dodge vehicles, or motorhome repair. Members often share invaluable experience, advice, and even scan copies of relevant service pages or manuals. Search for forums focused on classic RVs and Dodge vehicles. Engage with the community and ask specific questions related to your motorhome's components or issues.
3. Local RV Repair Shops: Experienced RV repair shops might possess some knowledge of older models. They could potentially offer repair services or point you towards appropriate manuals or resources. It might be beneficial to bring your motorhome to a mechanic familiar with vintage vehicles.
4. Libraries and Archives: While less likely, check local libraries or archives that might have collections of older vehicle service manuals.
