I have copped a few stone chips thanks to drivers who can't be bothered slowing for the one oncoming vehicle in a hundred kilometers, but I would not consider fitting a seventies-style stone guard over the windscreen. Bad enough having antennae in your field of view on long hauls.
Towing a trailer though, extended drawbar or not, you absolutely need some kind of protection at the rear of the vehicle. I've seen some vehicles with a few layers of cardboard taped over the rear window, probably works. I built the front box of our camper trailer in a shape that deflects stones down and to the sides, this has worked well. Not sure that I'd trust one of those trampoline arrangements.
