Well if it's a truck newer than 95 you won't find a conventional mount plate to fit it. Western doesn't make one. They only have the mounts for the newer minute mount style plows.
As for how well it will handle the plow. That depends a LOT on you. If you don't plow like a fool and pay attention to whet your doing it will handle it just fine. My plow truck is a 93 2500 and it has worn a plow every year since new. The only thing I have replaced that I actually attribute to the extra weight of the plow is a set of shocks and a steering stabilizer.
I would suggest that you add two items to the truck in addition to what it has if you plan on using the plow a LOT or if your hauling weight. One is an additional trans cooler with a separate cooling fan on it. Most of the racing type catalogs carry them as oil coolers for engines. Two is a good yellow beacon light. You will want it in operation when plowing and it doesn't hurt to run one if your loaded heavy.
