The kit is called the Crossbow, from Lehman Trikes
This is what the stock rear looks like for comparison:

Always loved the rear view of the Victory Vision.

Not quite the rolling couch of the Goldwing, but still nicely appointed.

Of course, I have visions of those rear hatches opening remotely revealing
automatic weapons pointed backward....but that's just me.

Anybody remember 'My Favorite Martian'?

(for those who don't, it was a TV show back in the 60's)

A friend of mine sells these at cruisin 66 here in town. Inside the triangle shaped cover on the right side of Victory's is a beer bottle opener, or was, i assume they still are! Huge giant pretty bikes though.

Thanks Ron -- I'll never be able to look at a Victory Vision again without cracking up...

Bozo the Vision,must have bin a childhood memory of the engineer.
