One thing I would be be VERY careful about, is to detach the body from the lens. On my first trips to AFrica, circa 2000, the road were so bad that if we left camera attached to a big lens, the mount would work itself out of the body. In essence the screws would come loose. Not a pretty picture to have the camera detach from the body for no reason. though the roads are much better today, I still do not attached a body and lens when travel long distances over rough roads.
