Here's another solution to the doors-off Jeep TJ mirror issue.
Buy a small "blind spot mirror" that has a sturdy metal mount (See examples in attached screenshots). At a hardware store, buy a suitably sized bolt, washers, rubber washers and a long hex "coupling nut." I bought a pair of mirrors on Amazon for $10, but only used one because the passenger side wouldn't be visible from the driver's seat. The hardware cost less than $5. Assemble as shown in photos.
The mirror is big enough to be usable, but small enough that wind hasn't been a problem. The unit has built-in angle adjustment. The rubber washers minimize vibration and help keep the nut from backing off. The long hex nut has enough surface area that you can install and remove with just fingers. After a few hundred miles of driving late this summer, it was still snug (next year I'll probably add a third rubber washer next to the nut just for good measure). I noticed zero vibration while driving. It's small enough that the unit drops in the glove box, ready for instant use when the doors come back off.
