2nd gen Tacoma to 3rd gen question

Question I have a 2nd gen Tacoma and I am considering a platform camper but was curious if I bought a 3rd gen Tacoma late on, is the only thing i need to replace the rear door or is there more to it? And/or are they not compatible at all?

Gen2 & Gen3 models are cross-compatible, and you’re correct, all you need to do is swap the rear panel.

Sweet thanks
