It will be interesting to see what they have to say. Found this link to a thread on another RV forum with the same question: https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/28988100/srt/pa/pging/1/page/2.cfm. Initially the poster says he heard of someone grinding down a pin in the steering column, which disabled the lock. His final post provides a different solution, similar to the thought going through my head:
"I finally saw a message on a Truck forum from a new series Tacoma owner. He tried to get at the factory locking pin on the steering column but it is not easy. The bolts have no head. They break the head off at the factory after installation. He then tried the following: "I added a battery disconnect switch, so after pushing the starter button once to put the truck in accessory (unlocking the steering wheel) I just pop the hood and throw my battery disconnect switch. Steering stays unlocked until battery power is restored. A setting saver maintains most of my settings while the battery is disconnected.""
Sounds like a battery disconnect would work, but it would create an issue if you wanted to use a supplemental braking system like a "Brake Buddy" that relies on 12V power from the toad to power a compressor. There could be workarounds to that too; just makes things more complicated.
