"There are several trailer dealers between Pueblo and Henderson, CO. I am glad I chose Complete Trailers. Brett went above and beyond to have my trailer delivered in time for Sturgis. Not only was the trailer delivered on time, he also added the cabinets that were a last-minute request! I received several compliments on the trailer and had a few people stop by to see the inside and ask a few questions. Brett is honest, knowledgeable and willing to go the extra mile to get the right trailer for you. Thanks, Brett for all your help and patience. "
