The following was a News & Insights report from the RV Industry Association (RVIA).
In 2025, California’s Advanced Clean Trucks (ACT) regulation, aimed at promoting zero-emission vehicles (ZEVs), will create a near-total “ban” on motorhome sales in the state, as well as in additional states that follow the California Air Resource Board (CARB) regulations. While the regulation does not specifically ban motorhome sales, the ACT regulation mandates manufacturers of medium and heavy-duty vehicles to sell an increasing percentage of ZEVs each year. This has led chassis manufacturers to halt sales of traditional internal combustion engine chassis for motorhomes in California, stemming from the lack of ZEV chassis suitable for motorhomes.
Since 2020, the RV Industry Association has been working with CARB on the ACT regulations through conversations directly with CARB staff as well as written and oral testimony at multiple public hearings. When CARB filed its proposed amendments earlier this year, the RV industry met with CARB staff to discuss the impact on the industry. The association also submitted comments laying out the negative impact of the regulation on the motorhome industry.
Unfortunately, CARB did not make any further amendment which would alleviate the problem of motorhome manufacturers being told by chassis manufacturers that they would not be able to supply ICE (internal combustion engine) chassis for sale into California since they could not offset their ZEV deficits by sales of a ZEV motorhome chassis.
Making the matter more complicated, it is not just the ACT that is causing the issue right now; it is the trio of regulations passed in the last two to three years: the ACT, along with the Omnibus Low NOx rule and the Advanced Clean Fleets rule. These three rules work together with the goal of gradually transitioning medium- and heavy-duty vehicles to zero emission vehicles (ZEVs) by 2036. We have commented to CARB on each of them, and also on the Small Off-Road Engine regulation, which threatens spark-ignition engines on generators.
The RV Industry Association continues to work with CARB staff on the ACT with their staff looking to hear more from our members and understand why chassis manufacturers will not be able to deliver products. While we are continuing to work with manufacturers, dealers, and CARB to find a solution, if nothing changes, motorhomes will not be able to be sold and registered in California beginning in 2025. The exact date is still to be determined.
Below are some FAQs on the Advanced Clean Trucks Regulation and how it is specifically impacting the RV industry and RV consumers both in California as well as other states.
