I can't say much about what year to get, but I would definetly recommend at least an extra cab. Double cab would be good too. Depends on how much stuff (or crap if you want) and people you want to take along with you.
I went from a '93 extra to an '04 double. I cleaned about 3 milk crates of stuff out of the '93, fire extinguisher, light, ropes, tie downs, chains, .... It was all stashed in the cubbie holes in the side wall, under the rear seats, in the rear seat foot well. And it didnt' look like a storage area back there. It all tucked away nicely. A third person could sit behind the passanger and not have to move anything.
There is no place to store all this stuff in the double cab. I had to go out and buy a tool box to put most of it in. There is that and a milk crate bungied into the bed. But I can take other people with me with a lot more confort.
Pick your trade off.
