Here's a Shadow 720 three horse slant gooseneck with the optional 5.5' extended dressing room & stainless steel front trim.  There's so much to talk about, it's hard to decide where to begin, but here goes...  This trailer is 6'9" wide and 7' tall and with the longer dressing room, it's 20' on the floor (17' is standard).  Aluminum frame, aluminum skin, extruded aluminum plank floors with integrated cross members every 6 inches, one piece aluminum roof, standard LED tail and marker lights, locking hasps on rear and escape doors.   Standard lined and insulated ceiling, lined & insulated walls in the horse area, 2-way vent over each stall, padded stall dividers with easy-to-use latches (and dividers are spring loaded to swing out of the way), telescoping divider & butt bar on the last stall, escape door with drop down feed door on the first stall.  Collapsible rear tack (and saddle racks can be used in rear tack or dressing room), large drop down feed door windows with independently hinged guards (you can lower the window & leave the guard up), large sliding windows along the butt wall, pass door from horse area to dressing room.  The trailer pictured here has the optional dressing room with 5.5' short wall and 9.5' long wall (3' longer than the standard dressing room), which gives plenty of room for tack, getting out of the weather or overnighting, and this longer dressing room even has a third large window as standard.  It's almost like stepping into a living room.  With the white walls and ceiling, the interior of this trailer is much brighter than our less-than-expert photography shows.  Standard stall width is 42 inches, which is wider than the stalls on many trailers.  The pictured trailer is also equipped with an optional 30 gallon water tank tucked up under the gooseneck.  There's more, but this writeup is already pretty long.  We invite you to visit Traveled Lane and check out the Shadows for yourself.
