Will the Diesel Ban Change Your RV Plans?

You’re thinking about buying a diesel motorhome, but now you’re worried the new emissions laws might make it a bad investment.

At Bish’s RV, we’ve been following this developing story since the beginning, and we’re here to help clear up the confusion.

By the end of this article, you’ll know how the diesel ban could impact RV sales, ownership, and camping — and what it means for your travel plans.

What Is the Diesel Ban, and Why Does It Matter?

The diesel ban, officially known as the Advanced Clean Trucks (ACT) regulation, is part of California’s effort to achieve zero emissions by 2035.

This regulation affects the production and sale of diesel-powered vehicles, including motorhomes.

States like Oregon, Washington, New York, New Jersey, and Massachusetts have adopted California’s stricter emission rules.

For RVers, this means:

Manufacturers may not be able to sell new diesel motorhomes in these states.
RV dealerships in these areas might face inventory challenges.
Current owners may see restrictions on registering or using certain vehicles in the future.

If you’re considering a diesel motorhome or already own one, this could significantly impact your travel plans and purchasing decisions.

Which RVs Are Affected by the Diesel Ban?

Not all RVs fall under the ban, but certain categories are particularly vulnerable:

Class A Diesel Pushers: These luxury motorhomes rely heavily on diesel engines for their size and power.
Super C Motorhomes: Built on diesel truck chassis, these models are also at risk.
Any RV Over 8,500 Pounds: California’s legislation could impact motorized RVs over this weight, which includes most diesel models.

While some smaller RVs and gas-powered motorhomes might be safe for now, the lack of clarity in the regulations has left manufacturers, dealers, and buyers uncertain about the future.

Why Did This Happen?

This all began in 2020 when California passed legislation giving the California Air Resources Board (CARB) authority to enforce progressive emission reductions.

These reductions aim for zero emissions by 2035, with significant milestones along the way.

How Big is a Motorhome?

Key points to know:

CARB regulations allow states to either follow federal emission standards or adopt California’s stricter rules.
The diesel ban stems from CARB’s recent clarification, which now affects manufacturers’ ability to produce compliant diesel chassis.
Major diesel chassis builders like Freightliner and Spartan are currently unable to meet the new requirements, effectively halting production for affected RVs.

If you’re planning to buy a diesel motorhome, here’s what you need to consider:

Limited Inventory: Dealers in affected states may not have new diesel motorhomes to sell after 2025.
Unclear Deadlines: The legislation doesn’t specify an exact start date, making it harder to plan.
Grandfathering Existing Models: Pre-owned diesel motorhomes with significant mileage (e.g., 7,500 miles) may still be registered in these states.

For now, buyers in non-affected states can still purchase diesel RVs, but long-term restrictions could make resale and registration tricky.

What’s Next for the RV Industry?

The RV industry has been actively lobbying for an exemption to these regulations.

Over the past year, discussions between the RV Industry Association (RVIA) and the California Air Resources Board (CARB) have continued.

Here’s where things stand:

Meetings in 2024 have yet to produce a finalized agreement, but discussions remain ongoing.
A new round of talks is expected in early 2025 to determine if exemptions or extensions will be granted for motorhome manufacturers.
The RV industry is pushing for clarity to help manufacturers, dealers, and buyers navigate this uncertain landscape.

For now, the future of diesel motorhomes in affected states remains unclear, but we’ll continue to monitor developments closely and provide updates as they happen.

Can You Still Use Your Diesel RV?

Current diesel RV owners shouldn’t panic — yet.

Here’s what we know:

Existing Models: Diesel RVs already in use or with significant mileage are likely to be exempt from new restrictions.
Camping Restrictions: At this point, there’s no indication that campgrounds will ban diesel RVs.
Travel to Affected States: Driving your diesel RV into states like California may still be allowed, even if new models can’t be sold there.

That said, it’s wise to stay informed as the situation develops.

What Should You Do Next?

If you’re considering a diesel motorhome or already own one, here’s how to prepare:

Stay Informed: Follow updates from Bish’s RV and trusted sources like RV Miles.
Explore Alternatives: Gas-powered RVs or electric models may offer a more future-proof option.
Act Quickly: If you’re set on buying a diesel motorhome, consider purchasing before stricter regulations take effect.
