Motorhome engines to cost more in Calif. Sign of the future?

Motorhomes with diesel engines to see biggest increase in costs

The California Air Resources Board (CARB) has approved a staff recommendation to adopt the so-called Low Nitrogen Oxide (NOx) Omnibus Regulation in order to attain the targets set in the State Implementation Plan. This regulation will increase the cost of engines used in motorhomes significantly starting with the 2024 model year, particularly those motorhomes with diesel engines.

CARB estimates that by 2031, the regulation will result in the lifetime cost of ownership increasing $8,841 for heavy-duty diesel engines and $5,814 for medium-duty diesel engines. These costs are associated with more stringent emissions certification standards, new in-use requirements, lengthened warranty requirements, enhanced durability demonstration requirements, enhanced defect reporting requirements, and increased diesel (DEF) consumption.

Unfortunately, CARB includes larger motorhomes in the same categories as heavy-duty trucks, even though motorhomes are driven significantly fewer miles each year.

THE NEW STANDARDS will be phased-in in stages starting in 2024. They will ratchet up in 2027 and again in 2031. The cost increase for gasoline engines is projected by CARB to be much smaller than for diesel engines. Gasoline engines are expected to see an increase of $411.

This new regulation will work in concert with the Advanced Clean Trucks (ACT) initiative approved by CARB earlier this year by providing a mechanism to create NOx credit generation to offset some of the required zero-emission technologies in the first year of the ACT regulations.

California was a great state at one time. I was born there but my family moved away when I was 14, in 1972 (I always thank the Good Lord for that). Poor governance and lawlessness has destroyed it to the point it may never come back. Most of my family have left to other states and those who remain, plan to. Crushing taxes, regulations, corruption, cost of living, fuel prices, overcrowding, pollution. I just quit visiting about 6 or 8 years ago. Just my opinion.

Yes, California is a one party system and NOT for working class. Nearly every piece of legislation benefits the poor, or even illegals, but not those who work. Job killing over regulation is the mindset of our whacko politicians! RVs will probably be Illegal not too long in the future here:(

People actually vote for politicians that push this insanity. They should not expect sympathy. An over the road driver I know has said his company has not accepted loads to or from CA in 2 years.

There has been proven extreme voter fraud in the last state vote. Also good ol Newsom passed a law that gives drivers license to illegal aliens, and shortly after that he passed another that automatically register all driver licenses for mail in voting. There was known well north of 500,000 illegal votes in just the Sacramento County last vote. And then the democrats supermajority got caught. But it was to late the votes were counted an the players in place.

As a resident of California this is just another nail in the coffin for the state. We are the only state in the union to have rolling blackouts due to increase in demand and a huge decrease in generating capacity due to closures of power plants the state deems unfit for their green new deal vision. Everything you pick up to buy from a spoon to a car has all kinds of warnings from this CARB bunch. Very sad state of affairs for California.
