An Overview of the Systems That Make RVs Livable—and How They Work Together

From luxurious Class A motorhomes to compact pop-up campers, RVs rely on a complex network of systems to provide comfort and functionality on the road. These include electrical systems like 12V DC and 120V AC, alternative power sources such as solar panels and generators, and essential fuel types—gasoline, diesel, and propane—that each play a unique role in powering appliances, heating, and mobility.

This certification serves as the foundation for understanding how these systems integrate and operate cohesively, ensuring safe, efficient, and enjoyable RV living.
