Re: Quigley Announcement on their website. Word for word.
Interesting. According to an auto web page, Advance Trak is $600 option for cargo vans. So if it isn't ordered the vehicles should still be able to be modified as before. SMB's web site lists several 2009s available for 4x4 conversion, but only those with the V-10 or diesel. I'm sure since Quigley's conversion process is certified by Ford (drop shipment of new vehicles directly from the manufacturing plant) that they can't alter or disable the Advance Trak system if installed.
Interestingly, it doesn't look like you can order a diesel in the passenger van anymore. Ford has to pay an emissions penalty (which is passed onto buyers) for the 6.0 PSD because the 6.4 PSD won't fit into the van. The diesel now costs $7,500 extra vs. $800 for the V-10. I winced at paying $5K more. $6,700 buys a lot of gasoline.
