If i take side roads, they are considered "bumpy" so I would need more ground clearance, but not necessarily in the off-road truck range. These may be gravel, mud, sand or anything in between. Most locals don't necessarily drive 4x4 trucks, although I'm sure most would like to. A jacked up road car would have plenty of clearance. I like that rally merc very much!

Checking this website it appears that the typical Ford Escape V6 and the typical Ford Explorer are sold all over Latin America.
Similar choices: Jeep Cherokee, Chevy Suburban.
Stay away from US and Canadian small pickups. All are different in Latin America. Full size domestic trucks are a good choice since they are the same down south.
