For awhile here in ON the ministry were stopping pickup trucks towing racecars on open trailers and weighing them and checking the combined weight. All pickups here are registered as trucks, same as vans etc without windows, and the only difference is the listed GVW. If under a certain weight(someone fill in the weight) you can get a sticker which states that the truck is mainly for personal use, but even with the sticker you are still subject to weight constraints. Another thing they are looking out for are people who use motorhomes to tow trailers loaded with flea market stuff, as they can consider it as a commercial venture.
