The HighRider is almost no more (except for a pile of parts in the shed...)
Here is what I did tonight (6-13-07):

After slicing (more like mangling...) the frame in two behind the center cross brace, I cut and fitted a replacement crossmember that the trailer's tounge will attach to.

A second crossmenber will be welded in place just in front of where the frame starts it's upward bend.
The tounge will attach to the bottom of these new crossmembers.
Cutting torches are FUN!
