My frame is 11 inches off the ground with the interior floor height 4 inches above that. Makes a nice position to swing out of the door, just like getting out of a normal chair.
I am using a 4" drop axle with 15 inch wheels. The overall height is 56" from the ground. I plan to pull my tear with a Nissan Pathfinder so the top of my tear is about 8" below the top of my tow vehicle.
