Keep the plow you have and use it.The truck will handle what ever V plow shy of a ten footer you want to put on it,that is based on experience. If you would like to listen to the advise of some designer whos worried about his butt and not your bottom line,the truck will hardly handle what it has on it and really they would not recommend plowing with their truck at all.If you listen to the advise given here you better sell the truck and buy a new 550 Ford with a six footer so you don't get picked up for overloading the front axle.Be cautious of the advise given here because it is all given by about 20 of us and there are thousand of plowers out there, take it with a grain of salt and hopefully you have enough experiance to weed out the bull.When you ask such a question as the one you did the experience and income is so varied that often very little of the advise is worth any thing and you have to base your decision on what you know to be true and what you see around you. Sorry so winded just getting a little tired again of people constantly saying what can't be done when it is being done and done successfully, and when they are so willing to give advise spending others money so freely(like trading in a brand new truck for one with a little heavier front axle, what kind of monitary hit is that poor sucker going to take, bad advise)So again I say keep your truck and blade and maybe spend a little money for some wings if you have the accounts to justify one.
