A frame shop would be my next stop. They have the tools to straighten your frame and beef up the now weak parts (from having been bent).
The bike is a killer; put a load at a significant distance from the rear axle and you have the lever arm from hell.
30 pounds of bike and mount might not seem like much but add the spare tire and bounce it up and down across 10 or 12 feet of thin metal welded into a frame and you get a tremendous amount of bending force at the axle attachments. Ultra-lite frames are not extruded I beams, they are welded up from strap steel.
Have your DW drive over that road while you follow behind in the car (at a safe distance) and watch that bumper, tire and bike rack. Be in for a shock.
