I am also not sure why there is so little advertising. I haven't seen any Cummins 600 ad (maybe I'm not watching the right programs) but have seen the new Duramax and PSD commercials. I would think DC would definitely want to let people, especially those in the 5 SO states, know about the newly available, most powerful engine available in a pickup truck. Now, I understand about maybe demand has already outstripped supply but I doubt it. The way I see it, the Ram is DC's number 1 vehicle, the number 3 vehicle of all autos sold last year. The money needs to be applied to it first. That goes for everything from advertising to R&D. The number 1 rule of business is "Advertise. "
Actually, last month Dodge Ram sales was up only 1%, far below that of Ford and GM. Regarding last year's total sales, Dodge was up 13. 9%, which was better than F-series and Silverado/Sierra. So, even with fewer configurations and a 45-state HO diesel, they still did very well. I know it sounds like I'm contradicting my previous statement above, but I like to think how much better they could do, if they just do it right.
