Dumb law, it will probably still be on the books after snow no longer exists......
On my 1983 truck I had a snow plow. Had to add an leaf to the front springs because of the weight of the plow. Used a heavy TC on it for several years with no problems at all. Can't say I ever tried to plow with the camper on it though.
And because I had a very heavy duty hitch welded to the frame under the rear for pulling a Bob Cat loader, I couldn't carry the spare tire in the holder anymore. I mounted it to the plow controls on the front end. It was lighter than the plow and worked very well there.
