I'm a member of a visiting Alaska group on Facebook, and I see a LOT of posts about people using Turo. Given its remoteness, Alaska has a limited supply of rental vehicles, and this was exacerbated in 2020 and 2021. I don't recall seeing anyone posting any sort of negative experience. I have no idea how it works or anything.
That said, if you're an owner renting your car like this, you'd better damn well be sure you have appropriate insurance because ordinary car insurance won't cover damages resulting from a personal car's use as a rental vehicle.
