Thank you! The bug deflector works great, it's a must buy if you do a lot of highway driving! The AVS model is available on Amazon: https://www.amazon.com/Auto-Ventshade-25053-Bugflector-2010-2018/dp/B003ZJ2HMM/ref=mp_s_a_1_3?crid=1USD248OD1V50&keywords=4runner+hood+shield&qid=1655667060&sprefix=4runner+hood+sh%2Caps%2C131&sr=8-3

Exact same thing happened to me on my last car. It came from another muddy/dusty pickup truck when they passed me, and some rock came loose on their chassis.
So after buying my 4runner, I also bought one of these: https://www.amazon.com/dp/B003ZJ2HMM which is great/cheap insurance because it will deflect most debris so that they won't hit the windshield. Good investment IMO.
Lifting the car a few inches might also help a little, if you happen to be planning to do that anyway.
