Spuda,
Yes, you are right, the electronics are housed in the cab, I could remove the module but if you heard all of the sounds you'd say "NO DON'T DO IT" as they are all very Star Wars like, if it was't for the single WAAALLLL-EEE sound amongst all of the others then it could literally be a SW vehicle.
I haven't taken it apart yet, but there are screws everywhere, which suggests that the parts should all be removeable. The cool thing about this truck is that the suspension lowers to allow access to the rear compartment, so I'm in a real quandry with what to do with it, strip her and make an air transport (hard option) or keep her as a ground vehicle and modify the existing layout. So, I've put it to the vote to see what the Yarder's think. I'll do whatever the results tell me to do.
