Exercise it
RV generators that sit for months are prone to fuel and starting problems. Many manufacturers recommend running the generator periodically under a load — check your generator's manual for its specific schedule and load guidance.
Watch the hours
Most RV generators have an hour meter. Use it to keep track of oil changes and other service intervals listed in your owner's manual.
Keep intake and exhaust clear
Generator compartments collect dust, leaves, and even mud-dauber nests. Check the compartment and exhaust before you head out, and never let exhaust collect near windows, vents, or under awnings.
Mind the heat and altitude
Southern New Mexico takes you from desert floor to high mountain campgrounds in an hour. Hot days push air conditioners and generators hard, and elevation reduces engine power. If your generator struggles more at altitude, that's worth mentioning when you ask for help.
Test your CO detector
Your RV's carbon monoxide detector is a critical safety device. Test it regularly, and never sleep with a generator running if the detector isn't working.
