The specific parts that should be replaced on an RV camper each year may vary depending on the make and model of the camper, as well as how often and how far it is driven. However, there are several parts that generally should be inspected and may need to be replaced on an annual basis to ensure that the RV remains in good working condition and safe to operate. These include:

Tires: RV tires should be inspected regularly and replaced at least every five to six years, even if they still have good tread, as the rubber can degrade over time and become unsafe.

Batteries: RV batteries should be inspected and tested regularly to ensure they are holding a charge and functioning properly. Depending on the type of battery, they may need to be replaced every two to four years.

Brake pads and rotors: RV brakes should be inspected annually and the brake pads and rotors may need to be replaced if they are worn or damaged.

Propane system: The propane system in an RV should be inspected annually for leaks or other issues, and any parts that are damaged or worn should be replaced.

Roof sealant: The roof of an RV should be inspected annually and the sealant should be replaced if it is cracked or worn to prevent leaks.

Water filters: RV water filters should be replaced annually to ensure that the water system is clean and free of contaminants.

Air filters: RV air filters should be inspected and replaced annually to ensure that the engine is running efficiently and that the air inside the RV is clean.

Awning fabric: The awning fabric on an RV should be inspected annually and replaced if it is torn, faded, or worn to prevent further damage.

It’s important to note that this is not an exhaustive list and other parts may need to be inspected or replaced depending on the specific needs of the RV camper. It’s always a good idea to consult the owner’s manual or a trusted RV service center for guidance on maintaining and repairing an RV.
