That is funny you say TaxaMassachusetts they do be raping in Taxs here. Trust me I live near a ski area that's how serious snow is in my area.. I can't wait to get a nice set-up going on this year or next year just tired of dealing with the snowblower okay I'll wait hopefully I'll find one soonSo I was curious because I've never heard of anyplace in Taxachussetts that gets feet of snow on a regular basis.
Annual average snowfall at cities, towns and parks in Massachusetts, including how many days it snows a year and the total amount of snowfall.www.currentresults.com
Most I'm seeing for an average is 80".
That truly is an amazing amount of snow.
One more "btw": the weight of the plow has nothing to do with the motor. If your truck can drive along OK with 2 adult passengers, then the truck will push a 500lb plow. Given the age of your truck, I can't tell you that you won't have an issue with the suspension sagging depending on how heavy the plow is. But the width of the plow isn't the only (or even most important) factor as far as weight goes - you can have a 7.5' plow weighing 400 lbs sitting on the side of a 7.5' plow weighing 780 lbs.
The motor might affect the 7' x 30" wall of snow you are trying to move. So waiting out a 24" blizzard before you start plowing will probably not happen with a small truck and small motor. But I suspect traction and counter weight (which is the same thing as ballast... ) will be a issue more than the motor.
You may also want to consider the fact that its quite narrow for a full size truck.Did you actually measure that plow yourself? Cuz to my knowledge, the 6' 8" only came in the plastic homesteader. That looks like a 6.5' minute mount one. If thats the case, then those used narrower special sets of pushplates for downsized trucks. A set to fit your truck doesn't exist.
If it hypothetically did fit, expect to spend anywhere from $1700-$2500 for the vehicle pieces installed
BTW, that plow is at least 23 years old. So factor that into the "good price" pro/con list
