In fact GM (not sure about Ford or Dodge) doesn't even put a system on duallys because there are too many wheels.

The TV monitoring systems are mandated on all vehicles less than 10,000 pounds, of all things by the "TREAD Act" (Transportation Recall Enhancement, Accountability and Documentation - don't you love government acronyms!). Beside the 10,000 pound limit, it exempts vehicles with a Gross Vehicle Weight Rating over 26,000 pounds, because they found the standard systems didn't work well with these heavy rated vehicles, which is why most Duallys don't have TPMS. Some interesting information about the TPMS rules and regulations, everyone should read.
Regarding your comment about rotating the tires, and reprogramming, for previous/current versions Dodge vehicles automatically sense the changed locations (after about 10 miles of driving) where the Ford and GM need to be reprogrammed manually. BTW, found that some places who rotate the tires charge for this reprogramming!!!! Simple to do, just look it up.
However, please check you vehicles owner manual - the forums information often last longer than information is accurate.
