Description
The Flagship Sierra, Lined, Insulated and Fully Matted
Trails West builds several lines, and the Sierra is the one that gets the standard equipment other models list as options. On this 2020 four-horse gooseneck that means aluminum wheels, anodized aluminum exterior extrusion, a stainless steel front that takes the stone chips a gooseneck always collects, and a horse compartment lined and insulated from front to back.
The insulation is not a luxury item on a four-horse. A lined compartment holds temperature better in both directions and cuts road noise noticeably, which shows up as calmer horses at the end of a long haul. Add the full matting inside and out and wood floors underneath, and the ride each animal gets is genuinely cushioned rather than just enclosed.
The compartment measures 7 ft tall by 7 ft 1 in wide on a steel frame with aluminum skin. Padded aluminum dividers with slam latches let one person sort horses quickly, drop-down feed doors on the head side and sliding bus windows on the tail side handle feeding and airflow, and each stall gets a two-way pop-up vent plus its own tie ring inside and out. Double rear doors with windows make loading straightforward and keep light in the back of the trailer.

The carpeted angle wall deserves a mention because it solves a small, constant annoyance: hanging bridles, breast collars and halters on a bare aluminum wall scuffs the leather and marks the wall. Carpet takes both problems away, and with the 4-tier swing-out rack in the side tack you can reach every saddle without climbing over the others.
Practical checks before you haul: look over the wood floor and lift the mats, inspect tire date codes, confirm brake function, and run the water tank to see it holds and drains. A four-horse gooseneck needs a properly rated truck with a bed-mounted hitch, and you should size your tow vehicle against the loaded weight with four horses and full tack rather than the empty figure.
