I own a Restoration and Repair shop in Wisconsin, and needed a trailer that was easy tp pull and easy to move around in the shop. After researching the many aluminum trailers I settled on a Primo. I liked the fact that the hardware is stainless steel so it will not rust because of our well salted roads during the winter season. The Primp trailer pulls easily behind my truck and the 18″ sides keep everything i haul in its place.
