Hi, I normally post in the FJ Cruiser Section, so this is new territory for me. I am currently building my FJ as a desert vehicle and am almost done and ready to start my new project within this year. I'm wanting to build a rock crawler and don't know enough about the 40 or 55 to make an educated decision as to which would be the best platform to start with, or an approx price I would be looking at to just get my hands on one of these. Any input would be greatly appreciated.
