There is no outright ban on RV sales in these states. Instead, manufacturers will need to comply with the emissions regulations or find alternative solutions, such as buying credits from other manufacturers with compliant vehicles.
Motorhome owners in these states can still register and operate non-compliant vehicles, but they will not be able to purchase new diesel-powered RVs that do not meet the updated emission criteria.
In summary, while RV sales are being restricted or made more challenging in these six states due to emissions regulations, there is no blanket ban on RV sales. Manufacturers and consumers will need to adapt to the new standards or find alternative solutions.
