I am wondering if the tow hitch can be added later. I notice only some FJs on the lots have the tow hitch in the rear. I do see the hitch bracket offered on the Toyota website for aftermarket items. I am mot looking to tow much, but the hitch is nice for different adapters like the bike rack and maybe to tow a jetski trailer at some point. Just wondering if it would be an easy add-on later.
