Hause, no not yet... I'm still thinking. I've found several 12' UTV ramps that are (I think) 18" wide and aluminum, but they are all $500+ I know a guy who has a set and I've been trying to get up with him to see how they work. He has a 1 ton box truck (one of the small Uhaul types) and he can put an ATV in it easily he says.
Monroe, all of our trailers, except my equipment (farm tractor) trailer all has racks in the front.
