Like @JenElio said everything except I4x4 can be added to a base or deluxe. I rather have a true locker than I4x4. Its seems to work just fine but I don't want a bunch of electronics on these things it's just more to tear up lol
Yeah get the 1000! I thought about a 700 for a little bit and quickly went back to thinking about the 1000 lol. I know I guy that has both and he says the 1000 is a whole different amimal! He says he still likes the 700 though
