hello all the users. I'd like to do a phantasy with horses, cows, ......i'd like to be transported in a big truck with them.

I think that would be rather uncomfortable, and smelly! :D

I have often thought of this fantasy too, however, it really would be smelly and nasty, but, that is one of the quirks. I'd always want to have some kind or invisiblity or some kind of hiding place, though, so as to not be seen by any of the people who would be unloading the load of animals at the end of the journey, and I'd of course want to have a way out, since all the clasps and locks are on the outside of the trailer.
