I agree with this. This is my main concern. Even if you use nipples as you mention it would be pretty hard to get the water out in a moving truck, also I am sure the truck will shake and cause the nipples to leak.I would not have water in the crates because of spillage and wetting of bedding. Rather I would stop periodically and provide water.
