"Ted,
Unfortunately, we do not have an ETA on when that one will be available. The coupler and adapter plate have been sent off to be machined, then once those get back to us we are going to test fitment and make sure everything functions properly, then after that we will have it released for production. If you check back in about 12 weeks we should have a better ETA for you. If you have any other questions, feel free to ask.
Thank you,
Kyle"

"Ted,
Unfortunately, no news yet regarding the 6-speed Tacobox, and I do not have an ETA. I thought a couple months out would be enough time at first. If you keep checking our website or the forum, that is where the latest information will be once we have made progress towards releasing that crawl box for production. I apologize for the inconvenience, if you have any other questions, feel free to ask.
Thank you,
Kyle"
I am considering selling my Tacoma at this point. I had a build planned. The TacoBox was the heart of it. Thinking of moving in another direction since this one has little chance of coming to fruition, apparently. Truck is sitting. I didn't buy it to be a mall crawler, dirt road cruiser. My Subaru Crosstrek is better at all of those things. At this point the Taco is WAY overbuilt for it's actual capability. It needs that crawl box to be what I need it to be. I have access to older Hiluxes with diesels; might make a move.
