Constructed during the 2008 model year, T.R.E. products were focused on building lightweight travel trailers. Ranging in length from 15 to 18 feet, T.R.E. travel trailers are all self-contained units that could be towed by most conventional passenger vehicles. T.R.E. travel trailers offered features such as air conditioning, microwave oven and a three-burner stove for basic camping enjoyment. T.R.E. trailers were produced under Columbia Northwest Incorporated.
