Our Legend has stock sides that are high, starts
about 5 ft above the floor, with solid doors on the back with a small
bus window in each, about 1 ft x 1.5 ft. They can see more out of the sides than
the back. They still prefer to ride backward most of the time, but they like to
peek out the window occasionally.
Every time I leave a horse loose in
the trailer, they are facing backwards when I check on them. Some will turn
around even before I get into the truck. I wonder if they would do it in an
enclosed trailer? Mine is a 2H slant load, stock type
so they can see out the back more than they can see out the side
rails.
