I don't understand what a racing only series would bring to the table that the many other mixed discipline series already do.The only thing I can see from your ideas that might be unique is the field size, assuming that's 20 trucks on track at once. We've already seen that more than 2 in a stadium doesn't really work, in which case you have to go to speedways. Monster trucks have no business racing as a pack on an oval track for a wide variety of reasons. If you mean a head-to-head bracket competition like we have from pretty much every promoter today, how do you fill the time left over from cutting out more than half of the elements of the show?
