Explain how that affects the paint? A trailer is either on the bumper or on tow hitch which have nothing to do with the paint. Even hauling stuff in the bed if you aren’t a complete Moran, you wont scratch anything but your bed. Most trucks sold are 2wd so people aren’t using them in the rest of your post. 25% of them fall under that not 75% maybe in your area, but not for the majority of the US.75%. who knew.imagine that.75% of all trucks never towed a boat,travel trailer,utility trailer , orv/atv trailer,never carried a snowmobile,hauled a load of junk to the landfill,never carried anything in the bed,no transfer tanks,construction equipment at all,never been off road.never get used for snow clearing,never get used as a winter driver.that is a crap ton of grocery getters.sure you didn't mean 5 % ?
