I mis-spoke above, my trailer is a Contential Cargo...

My trailer is an enclosed and the rear door is the loading ramp, it is prabably about a foot and a half from the ground. It does not tilt and I usually load the roadster after the trailer is hooked to the truck. I am not even near bottoming out. I borrowed an open trailer a couple of times prior to buying my own. I did drag the oil pan but only because the ramps were too short. I don't think that highboys are really all that low compaired to most other hot rods, you should not really have many problems loading your roadster on a trailer...
