Travel in style in a new RPM bumper pull trailer. A Trails West RPM bumper pull trailer comes standard with line and insulated walls and roof to lock in the heat when equipped with an optional furnace. The custom designed arched floor allows for simply drainage of water from melting snow off of the sleds. Customers have commented that this trailer far exceeds their expectations. Our bumpers pulls are offered in a 20 or 28 ft. size.
