Hector........there's a 18 foot enclosed trailer, Indigo Blue for sale on RaceJunk that's here in Dallas per the following link. I'm looking for a 20ft but I think a 18 ft still would be fine for a Cobra. Race Junk seems to be good site for used trailers. Everything I seem to find however is across the country ie; found a real nice 20ft in Troy Michigan..........
