Sadly, Toyotas are NOT
Sadly, Toyotas are NOT engineered for the stresses of offroad driving. Any damage sustained while driving a Toyota off-highway will be deemed "abuse" and not covered under the factory warranty. A buddy of mine took his brand new FJ Cruiser on a mild offroad trail and the flexing cracked the frame. This happened to a lot of FJ Cruisers (Google "FJ Cruiser Cracked Frame") and Toyota charged their customers for the repairs.
