Kyle Busch truck team going to Chevy  

Stew's truck team was very excited switching to Toyota and alligning themselves with Kyle Busch's KBM and Toyota engines which were dominating. At the same time, NASCAR announced the Illmor engine mandate which took a lot of advantage away from the Toyota culminating the 2020 pandemic year of no practice, this really set them behind big time.

Like guys have said, manufactuers dictate who runs what and how much support the teams get. Stew's team was at the bottom of the totem pole, but now move up a level as KBM exits. So it's a good thing for Halmar- Friesen.
