I absolutely adore these little guys and honestly really want to keep them into late-game K2 as mall suppliers or little tiny tasks around the base as the big trains haul the massive loads
But I can't really do it to the extent I want if the trains can't make use of the K2 equipment grids and fuels.
6x8 would be somewhere around balanced against the 12x12 of full size trains' equipment grids, and since K2 nerfs every other fuel in the game, not being able to use the K2 vehicle fuel hurts the little guys even more, and I want to be able to actually have fun with this incredibly fun little mod.
