RVIA Economic Impact Study

The Recreation Vehicle Industry Association commissioned an Economic Impact Study on the RV industry, released on June 7, 2016. The study found that the RV industry contributes about $49.7 billion in economic output or 0.28 percent of the Gross Domestic Product. Through its production and distribution linkages, the industry impacts firms in 426 of the 440 sectors of the United States economy.

Nationwide, the industry is responsible for 216,170 jobs, both directly and inderectly, creating an economic impact of $37.5 billion. The full study results, along with each individual state and congressional district's economic impact is available on the website by clicking here .

California Raises Standards on RV Diesel Engines

Last week, the California Air Resources Board (CARB) adopted a proposal that will result in the heavy-duty (HD) engines used in motorhomes needing to have more sophisticated on-board diagnostics (OBD) systems in the future.

Engine emissions will be monitored by a Real Emissions Assessment Logging (REAL) process. REAL will require vehicles to collect and store data collected by nitrogen oxide (NOx) engine sensors currently used with diesel engines. This will let each vehicle track its own emissions performance as an alternative to lab testing. Existing sensors will also track CO2 emissions data to assess fuel consumption and greenhouse gas (GHG) emissions.

The change will cause higher engine costs. CARB projects an additional cost of $43 per engine due to the amendments, although these costs will be affected by how engine manufacturers certify their OBD systems. CARB estimates that the amendments will approximately triple the cost of certifying OBD systems with deficiencies. In the future, an engine with the maximum possible number of OBD system deficiencies could incur added costs of $1,250 per engine.

This increase in penalties is intended to force manufacturers to design their OBD systems to comply with all requirements, which is currently not the case. Today, because the penalties for deficiencies are low, it is common for manufacturers to certify non-compliant systems and pay the penalties for deficiencies. The burden of compliance with these new rules will be on engine manufacturers, not motorhome manufacturers, CARB says.

Existing NOx sensors will estimate and track emissions on medium- and heavy-duty on-road diesels. The rule also requires engines to log engine activity data (e.g., work, speed), which will be stored on both a recent and lifetime basis. That requirement will be enabled by GHG data tracking using existing technology and data on vehicles and will apply to all on-road HD engines.

Based on industry concerns about lead times and cost, some provisions of the rule will be postponed until 2024.Manufacturers will also have two options for implementing REAL. The first calls for certifying OBD systems at a reduced compliance level in 2022 or 2023. The second option lets manufacturers certify OBD systems for full REAL compliance in 2022 but will apply reduced OBD testing in 2022 and 2023.
