[DeTomaso] Car Trailers

Anyone know where you can rent an open car trailer (tongue, 5th wheel or gooseneck) long enough to carry two cars (75 Corvette & 71 Pantera). I am in SoCal and need to go get my cars that are up in Seattle. The usual places like U-Haul, Ryder & Pensky, won't rent for a Corvette or Pantera (they say they don't fit) and they only have trailers long enough for 1 car. Thanks Roydon
