Buying Guide: Key Purchase Considerations
Power needs: Assess your RV’s total load, including air conditioning, heating, water systems, and charging requirements. Larger units handle whole‑home or busy camp setups, while smaller portable options are ideal for basic essentials.
Fuel options: Diesel, gasoline, and propane each have pros and cons. Diesel offers durability and longer shelf life if properly stored, but fuel availability can vary. Dual‑fuel or tri‑fuel models provide maximum flexibility for travel across regions.
Runtime and fuel capacity: Look for larger tanks and efficient engines to extend half‑load and full‑load runtimes. Inverters provide cleaner power for sensitive electronics and typically run quieter than traditional generators.
Portability and setup: RV users benefit from wheels, handles, and compact footprints. Electric start improves convenience, especially when you need power quickly at a campsite or during an outage.
Safety features: CO watchdog sensors, over‑load protection, and protected outlets reduce risk in enclosed spaces. Consider automatic shutdown features and weather‑resistant housings for durability in diverse environments.
Fuel availability and maintenance: Ensure access to spare parts and consumables. Diesel models may require different maintenance routines than gasoline or propane units. For diesel systems, consider maintenance kits like those designed for Onan Quiet Diesel to extend life and reliability.
Warranty and support: A strong warranty and accessible customer support help safeguard your investment on long trips or frequent use.
