Hello Pete,
Recently purchased a Liberty Garden Hose Reel model 840, 541-632. It is constructed as on a four wheel platform. I could not recommend this item. There were 2 major issues, upon completing the assembly I started to crank the reel to take up the hose. To my amazement the crank just kept on spinning, the 1/2 inch pipe thread handle that attaches to the reel striped the very first time! They advertise a powder rust resistant paint. The inside of the tubes appear to have already start to oxidize, this is rust. The assembly process also caused some paint to chip easily, which will quickly start to rust. The profile of this cart is a good idea but the implementation is poor. I am glad I bought it at Home Depot because of their good return policy and friendly staff.
