In addition to vehicles, I would love to see trailers such as campers, boats, kayaks, jet skis, etc. Would be a lot of fun to have a range of recreational trailer options to tow with SUVs, trucks, and station wagons. Trailer hitch receivers should be something you can add to your vehicles. Perhaps each car in the game could have its real-world towing capacity plugged into the game, and you should be able to tow any trailer within that vehicle’s tow rating. Also, you should be able to increase your vehicle’s tow rating by adding stiffer rear springs/shocks, a transmission cooler, and bigger brakes.
