I have a first gen Sequoia 4x4. It is overlooked as an adventure / off road vehicle. This is what I find online. I will take a tape measure to it when I have a chance:
Ground Clearance: 10.6 in.
Approach Angle: 28 deg
Departure Angle: 20 deg
This article has ground clearance at 9.0

I doubt I'll get stuck.
