Curtis has been around for about 5 yrs making plows. Have never heard to many bad things. They are located in Worcester Mass, and have made tractor cabs for many years. Their first gen of v boxes were bolted together, that didnt last to long, and now are welded.
I have a Curtis (Sno Pro 3000) plow on my truck. I do only residential stuff so I have the smaller 7 1/2 ft model. I have no problems with the plow. If you have some specific question about it, let me know and I'll see if I can help you out.
