Complete Buying Guide for Aftermarket RV Generators
Essential Factors We Consider
When evaluating aftermarket RV generators, we focus on several critical factors. Power output must match your RV’s electrical needs, with sufficient surge capacity for startup loads. Fuel efficiency and runtime are crucial for extended trips. Noise level matters for campground etiquette, while portability affects storage and transport. Safety features like automatic shutoff and low-oil protection prevent damage and ensure reliable operation.
Budget Planning
Aftermarket RV generators range from budget-friendly options under $500 to premium models exceeding $2,000. Consider not just the initial purchase price but also fuel costs, maintenance expenses, and warranty coverage. Entry-level models work well for basic power needs, while mid-range options offer better features and reliability. High-end generators provide maximum performance but require careful consideration of your actual power requirements.

Investing in the right aftermarket RV generator transforms your travel experience from limited to unlimited. The peace of mind that comes with reliable power cannot be overstated. Consider your specific needs, budget, and camping style when making your selection. The generators on this list represent the best balance of performance, reliability, and value in their respective categories.
Frequently Asked Questions
Q: What size generator do I need for my RV?
A: Calculate your total power needs by adding up the running wattage and starting wattage of all appliances you plan to run simultaneously. Consider surge requirements for motors and compressors. For most travel trailers, 2000-3000 watts is sufficient, while larger Class A RVs may need 5000+ watts.
Q: Can I run my generator while driving?
A: Some portable generators are designed for vehicle use with proper mounting and ventilation. However, most RV generators are meant for stationary use only. Check your specific model’s specifications and local regulations before attempting to run while moving.
Q: How often should I maintain my RV generator?
A: Regular maintenance is crucial for longevity. Change oil after the first 20-50 hours and every 100 hours thereafter. Clean or replace air filters regularly, check spark plugs, and inspect fuel systems. Follow the manufacturer’s maintenance schedule for optimal performance.
Q: Are inverter generators better than conventional ones?
A: Inverter generators provide cleaner, more stable power that’s safer for sensitive electronics. They’re typically quieter and more fuel-efficient. However, they generally cost more and may not provide the same power output as conventional generators for high-demand applications.
Q: How do I choose between gasoline, propane, or dual fuel generators?
A: Gasoline generators offer the most power and availability but have shorter shelf life. Propane provides cleaner burning and longer storage but less power density. Dual fuel models give you flexibility to choose the most convenient option for your situation and availability.
Finding the perfect aftermarket RV generator is about matching your power needs with your lifestyle. Whether you’re looking for maximum power for a large Class A motorhome or quiet, clean power for a compact travel trailer, there’s a generator on this list that will serve you well. Remember to consider your specific requirements, budget, and camping preferences when making your decision.
