RV Generators

What types of RV generators do you carry?

Our RV generator selection covers portable inverter generators for tailgating and boondocking, along with replacement parts for built-in motorhome gensets. You'll find units sized for running a 13,500 or 15,000 BTU air conditioner, charging house batteries, and powering kitchen appliances. For backup power planning, pair your generator with a quality surge protector and proper adapters from our RV plug adapters collection.

What size generator do I need for my motorhome?

Size your generator by adding up the running wattage of everything you plan to power at once. A single 15,000 BTU rooftop air conditioner typically needs around 3,500 starting watts and 1,500-2,000 running watts, so a 3,500-4,500 watt inverter generator handles most Class B and Class C setups. Larger Class A coaches running dual AC units, a residential refrigerator, and a microwave usually need a 5,500-7,000 watt onboard generator. Confirm your AC's startup draw before ordering.

Do you sell parts for older or used RV generators?

Yes. We stock common service parts for Onan, Cummins, and other onboard RV generators, including air filters, oil filters, spark plugs, and control components. If you're servicing other systems at the same time, check our RV electronics collection for transfer switches, monitor panels, and related power management parts. Have your generator's model and spec number ready when you call, that's the fastest way to confirm the right part.

How is shipping handled on RV generators?

Smaller portable inverter generators ship standard ground. Larger onboard units and heavier gensets ship via truck freight, and the freight cost is noted on each product page. Orders over $100 on qualifying parts and accessories ship free. If you need help confirming fitment or freight timing, text or call our team at 817-984-1852 before you order.
