The MHERO 817 is a military-derived off-roader, and its high-voltage system is sealed for water crossings, which is the part a general garage misses. Muscat is humid and sits on salt air; an hour inland at Nizwa the heat is dry; up on Jebel Akhdar it is cool enough to need a jacket. A pack driven over one weekend can see all three, and each of them stresses a different part of it.
We check it against all three, and cover sealed high-voltage systems after water and sand exposure, plus off-road drivetrain work.
