Monaco Counters Last Week’s Pro-SCR Letter
Editor’s Note: Monaco RV LLC President Kay Toolson and Navistar North American Truck Group President Jack Allen have issued a response to a pro-SCR letter distributed last week by several motorhome builders utilizing Freightliner Custom Chassis Corp. diesel chassis. Both SCR, which Freightliner employs, and EGR diesel-powered platforms, which Navistar has developed, are a technological response to the Environmental Protection Agency’s more stringent 2010 diesel emissions standards. Their letter follows.
THE BEST 2010 EMISSIONS SOLUTION IS ADVANCED EGR
To all Recreation Vehicle dealers (US and Canada):
Why are so many RV manufacturers pointing at Monaco RV? Think they are worried? They should be! EGR is a proven technology and the latest advancement in emissions control for the next generation of diesel engines. SCR is not.
We were shocked and disappointed by an open letter that was recently signed by seven RV manufacturers, claiming SCR as the best 2010 emissions solution for customers. We disagree. Advanced EGR is the best solution for customers because it is as simple as turning the key. At Monaco RV, we’ve never been about following the crowd – we build products based on what’s right for our customers.
In their letter, there are claims that are either outright lies or don’t make sense.
- Exhaust Gas Recirculation (EGR) is a proven technology that has been in use for years. NavistaEGR to the next level. It is a simple, no‐hassle solution.
- Navistar has delivered over 20,000 Advanced EGR‐equipped vehicles, including Monaco RVs.
EGR is Simple
- Advanced EGR doesn’t require additional components or complexity to operate a motorhome. Our customers won’t need to change anything about the way they go RVing.
- EGR doesn’t require “DEF” (urea) to run.
- MaxxForce engines in Monaco RV products are fuel‐efficient, quiet and powerful. Their letter claims that SCR elivers better fuel economy. Compared to what? Themselves?
The only thing the group’s SCR letter was right about is that Monaco RV is the only manufacturer to offer its customers Maxxforce Advanced EGR in an integrated coach product. Which makes you wonder: Why would seven manufacturers feel the need to write an open letter making a case for SCR? What are they worried about?
The answer to this question is anyone’s guess. But we can tell you why we chose the Advanced EGR solution. It’s simple: It reduces NOx inside the engine and it requires absolutely no changes to the way our customers go RVing. In other words, we put the customers first by utilizing a technological solution that is right for their needs.
And while we’re on the subject, here are some things you may want to consider about SCR and the required Diesel Exhaust Fluid (DEF):
- Running out of DEF causes the engine to derate and eventually shut down.
- At low RPM levels, such as at idle, SCR doesn’t work, creating higher, pre2007standard level emissions. Think about coach owners sitting in campgrounds or in traffic. This is a step backward for clean air.
- DEF freezes at 12 degrees F and storage isn’t recommended above 77 degrees F.
- DEF (urea) is a hazardous chemical.
- DEF and related components add to the complexity and cost of operating motorhomes.
