California’s Gas Generator Ban: What RVers Need to Know (and How to Prepare)
By Del Albright, Land Use Advocate and Sustainable Motorized Recreation Enthusiast
California is charging forward with bold air quality regulations aimed at reducing emissions across the board—including portable gas-powered generators. While the state’s intent is clear—cleaner air and reduced environmental impact—the implications for RVers, campers, and off-road adventurers are complex and far-reaching.
This post breaks down what the ban means, what the RV industry is saying, what your options are for staying compliant, and why fire safety is becoming a major concern—especially in tightly packed areas like the Glamis sand dunes and other snug RV camping spots.
The Ban in a Nutshell
In 2021, California passed Assembly Bill 1346, directing the California Air Resources Board (CARB) to phase out small off-road engines (SOREs), which includes gas-powered portable generators. The timeline is as follows:
- By 2024: New small engines must meet stricter emission standards.
- By 2028, The sale of new gas-powered portable generators under 25 horsepower will be prohibited in California.
Importantly, the ban only applies to the sale of new units. If you already own a gas generator, you can continue using it.
️ What This Means for RV Owners and Campers
RVers—especially those who boondock or overland—have long relied on portable generators to keep rigs powered when off-grid. Here’s how the regulations affect you:
- You can still use your existing gas generator. The law does not require the removal or disposal of current equipment.
- You won’t be able to buy new gas generators in-state after 2028. If you plan to upgrade or replace yours, you’ll need to explore zero-emission alternatives.
- Out-of-state purchases may still be legal but could run afoul of local enforcement rules in the future.
What the RV Industry Is Saying
The RV Industry Association (RVIA) has raised concerns about these regulations, primarily focused on feasibility. They argue that while zero-emission goals are admirable, most RVs—especially larger units with onboard air conditioning, refrigeration, and charging needs—still rely on internal combustion generators.
RVIA and manufacturers are engaging with CARB to request the following:
- Flexibility in timelines for built-in RV generators
- Technology-neutral pathways that still allow for propane-based or hybrid options
- Expanded incentives to ease the financial burden on consumers
Some manufacturers, like Winnebago, are already experimenting with all-electric RV prototypes, but these are still niche offerings with limited range and high costs.
⚡ Zero-Emission Alternatives for RV Power
If you’re preparing for this shift, here are your main options:
Lithium-Iron Phosphate (LiFePO₄) Batteries
An increasingly popular solution, these batteries are known for:
- Greater capacity and deeper discharge ability
- Faster charging times compared to lead-acid
- Longer lifespan, saving money in the long run
- Lower fire risk compared to other lithium chemistries
But it’s not all sunshine and solar panels…
Lithium Fire Risks: A Real and Growing Concern
While LiFePO₄ batteries are safer than standard lithium-ion (like lithium cobalt oxide), no lithium battery is entirely without risk. Lithium battery fires—especially in high-heat environments—can be intense, chemically reactive, and hard to extinguish with conventional firefighting tools.
This is especially critical in places like Glamis, where RVs are often packed closely together, temperatures soar, and lithium power systems are becoming more common. In such conditions, even a single battery overheating can threaten multiple rigs, lives, and acres of public land. Combined with the current lack of on-site fire protection in these areas, this creates a serious and growing wildfire risk.
Fire safety tips for RVers switching to lithium:
- Follow manufacturer installation guidelines and never cut corners.
- Use fireproof battery boxes or enclosures.
- Never store batteries in direct sun or unventilated compartments.
- Avoid DIY installations unless you’re trained and confident.
☀️ Solar Integration: The Long-Term Answer?
Many RVers are now pairing lithium banks with solar panel setups. These systems can reduce or eliminate the need for any generator—but they require upfront investment and careful design. Solar energy may be enough for light-duty off-grid users or weekenders. For hardcore boondockers, hybrid systems (solar + backup battery or generator) will remain essential.
California Offers Tax Incentives
To soften the blow, Assembly Bill 921 (introduced in 2025) proposes a tax credit of up to $3,500 for individuals and small businesses transitioning to compliant backup power systems. This could include solar/lithium combos or other CARB-approved equipment.
Stay tuned to CARB’s announcements for implementation dates and application guidelines.
️ Final Thoughts: Where We’re Headed
California’s generator ban is part of a larger environmental push, but it puts real pressure on RVers who value independence and off-grid travel. It also underscores the need for better fire protection and emergency infrastructure in remote recreation zones like Glamis and other tight-fit campsites, where fires—especially from lithium batteries—can escalate quickly and dangerously.
RVers and overlanders can rise to the challenge by:
- Learning their options
- Upgrading safely and smartly
- Advocating for both access and safety on public lands
Clean energy can and should be part of our outdoor lifestyle—but education, infrastructure, legitimate alternatives, and common sense must back it.
