Since the Lexus GX 460 we had didn't have the rest of the trailer hitch, our option was off-road. Kelsey knows how a rock crawl, the air ride only raised the rear so that didn't help with rock clearance. Did make it ride rougher, so we lowered it to the normal air setting. As a luxury Lexus it's a cousin to the Toyota 4Runner. Similar size. Yes it's a truck with "body on frame."
