If you buy for PC it doesn't matter. The dev console will allow you to use the player.additem code to give yourself whatever pack you want to.
Or load an ESP that fools the game into thinking it was preordered somewhere else.

My understanding is that you input the code somewhere and then DL the items. Which means you won't beable to player.additem them. The canteen and the binoculers are attanable in the game, the only thing in the packs that you can't get in the game are the weapon and the armor. And that's just to say you can't get that specific weapon or armor. There will be other 10mm pistols but only one weathered one with that texture, there will be other shotguns but only one with that texture, etc etc etc. And yes, modding in the pre-order items are usally against the rules.
As for me, I voted the caravan because that's the one I like the most. I'm going to be getting the classic caravan though... that is to say that my collectors edition has been pre-ordered via Gamestop with a second copy pre-ordered via Wal-Mart, the pre-order code will be kept while the game will be Christmas gifted to my brother.
