The only scratches on my drums are from the 1 time I didn't transport them. (no money for cases for a 10-piece)
Having said that, get hard cases if you can. I had Humes and Berg before, but SKB makes a nice case too.
As for cars... you don't need a "huge truck like a Toyota or Nissan"... in fact, don't get a 'Yota or Nissan to begin with... I've fit my 10 piece in a 1987 Bronco, Focus wagon, Ranger with 6' bed, minivans, cargo vans... I've seen bigger sets in a regular 1996 Civic sedan (minus the passenger seat).
I've fit smaller set-ups in a Hyundai Accent, easily.
If you get a pick up, get a camper shell or tonneau cover. If you have a SUV, wagon, whatever... try and cover the stuff up. People will break into your car and steal crap in a heartbeat (at least the will around here, that's why I'm beefing up the windows in my camper shell).
Just make sure you don't have too much room as things like to fly across open spaces and get damaged, but have enough room so things aren't pinched and getting damaged. Also, playing with Legos and the like, or Tetris, as a child probably helps.
