There are only right now 12 fully funded Truck teams going into this year. Did you also see that they are going to make teams use the same engines two weeks in a row except on the plate tracks? It may be too late to save the Truck series in its current state but NASCAR is in panic mode and is at least trying.
Helping teams with this new engine thing as well as the new pit road rules and limiting team numbers in travel are all fine with me. When the series first started they did indeed not really have traditional pit stops. They had a "halftime" and stopped the Trucks for 10-15 minutes and let the crews make adjustments. This kept teams from having to have a pro pit crew and limited the number of tires used significantly helping to keep costs down.
This tires or fuel strategy will be interesting to see how crews handle this. It may seem stupid but having 15 trucks show up at California would be suicide for the series. I saw that with these new developments and people hearing of what was coming there may be 8 or 9 more trucks instantly because of this. A couple of brand new teams and a few teams going to run another Truck.
