I bought this product from Northern tool. They sent me an open box that was missing parts. When I contacted them about it, they basically told me "too bad".
I contacted Boxer Tool directly and within an hour had a working solution to get this device working, and had the spare parts within 24 hours of contacting them.
Today I installed the product and picked up 2 yards of Mulch in my full sized Dodge pickup. Unloading took about a minute. Amazing tool for moving heavy loads out of a truck. Do yourself a favor if you tend to move bulk in your pickup, buy this!
