"I shopped around Colorado for a good deal on a nice, well built trailer and found Complete Trailers to have exactly what I needed. I got a beautiful 14x7 with no hassles or gimmicks. They have the best looking and best built trailers, very high quality compared to some of the others I looked at. These folks are worth the drive and check them out before you buy. Jeremy was the person I dealt with - but all the staff were friendly and knowledgeable. If I ever get the $$$ for their aluminum version, I will be back for that one!"
