These are just excerpts from truck files but weight is generally located (Bold is what you are looking for):
globals
5000, 0.0, GravediggerBand

Also there is a node that deemed as a "load" (basically used as a center of gravity weight placement for the monster trucks)
nodes
98, 0, 0.2, 0, l 1900

Traction related changes are made here (1.3 is front, 1.8 is rear):
set_node_defaults -1, 1.3, -1, -1
