Plowing a personal driveway with that truck is no problem. I got a Western HTS which is fairly light. My truck handled it like a champ. I put Timbrens on the front to limit sag. I also threw a couple sandbags in the rear when plowing just to keep the truck level. I always took care to be gentle on the transmission, not hitting the gas until it was fully engaged. I used that setup for about 5 years, never hit snow I couldn't move with it in Wisconsin.
I have no advice regarding the magneride, though.
If you're serious about it, I recommend looking at the plow brands you can get serviced locally. I ultimately chose Western just because the receivers come off, so in summer you don't have any brackets hanging down below the air dam. I had mine trimmed around the brackets, so you would want to see how the front end of your truck will get butchered up to fit the truckside mount on there.
If you have any other questions, hit me up. I researched the heck out of it before I pulled the trigger on mine.
