Swear to God, this is absolutely true. Had a friend who had a RAV4. No tow package for low end torq. So... waited a few months, spotted a programmer on Craigslist, said it had tow mode. It had 4 more models too. Super tow, super economy and stock. Buyer was beside themselves, learned how well they worked, and would switch to super eco on one ramps. ( really a bad idea, so they stopped...)

Hacking is a good thing.
