I know that there are some light-duty plows with aluminum blades (i.e. snowsport).
However, I do I run a stainless wear-edge on the small plow I use on my compact tractor. I don't want the plow-scrape shavings that rust and turn into brown scrape marks on my new concrete driveway, Also I don't have to worry about leaving a rust stain line on my garage floor where I park it.
Stainless steel snow plows seem to be a thing around here. My nephew had one and all the big boys do too. Center pivot is the most fun type, called a V plow. Probably around $5,500 installed on a “normal” truck. I hope those clever California engineers make a provision for us North Easterners.
I need a snowplow on mine also. I sent a question to Tesla about two months ago and haven't heard anything back. If it can't have a plow mounted then It will be only 50% value to me because I do plow about 65 customers with our current trucks. We would use this for local driveways and small businesses close to home. KDN
