Really depends how you use it, I had a 7. 5' Fisher minute mount RD plow on a '97 GMC half ton that was not rated for a plow and never had a problem. I was always pretty carefull, did not try to push back large frozen banks, always came to a full stop before shifting from forward to reverse, ect. . I did it for fun, just a couple driveways, I was pretty amazed what it could push without really trying. I sold the plow when I got the Dodge, just too much hassle. If you are going to use it to make money you probably have to be harder on the truck to the jobs done quickly or if you are plowing large lots it takes a good amount of momentum to keep the pile going which can be hard on the truck. I got the plow package on my Dodge, if I wanted to plow with it I would not worry about hurting it, it's 10X tougher than the GMC I had.
