3ds Max :: How To Add Vehicle To Resource Kit (attached FBX)

I tried to add a vehicle to the resource kit (attached FBX).
Used the resource kit manager .. it almost worked .. final object did not appear, I got an emoty box where the truck was supposed to be.

then I tried to copy materials from an existing vehicle max, merged the 2 models in one max but could not find a way to 'copy' a material from source to target .. source appeared to be 'loacked' like a group

then I tried to make a copy of the toyota dyna truck - but scaled up a little (120%). Managed to scale up object but result in road model had the original scale??
 
Basically, the toyota dyna truck is too small. I need a real size delivery truck in Civil View or I need to be able to scale up the dyna truck. Steps on how to add a vehicle - including material settings would be useful.
 
Note.. in 2 and 3 .. the existing vehicles in max files, seem to be grouped somehow - what is used? How do you ungroup it? (it is not a 3ds max group)
