Might be a good idea to actually measure. Changes to the suspension or tires, as well as any optional or aftermarket roof appendages, might cause the current height to be different than the original spec.
If you or someone you know has a 4’ level, get a step ladder, rest one end on the highest point, hold it level out over the edge, and drop a tape measure to the ground. If you don’t have a long level, a 2x4 with a shorter level on it will get you close. Easier with two people.
Add 6” margin of error, and stick it on the dashboard somewhere handy.
