OK Pop... This is what I have considered:
  • 3200/3600 box (possibly a 3800 -- sides are hard to find but can be fabricated out of a couple of extra bedsides) to -help- accomodate motorcycle wheelbase
  • modified frame and bed crossmembers that allow a low center channel (dropped bed floor in center) -- may be necessary to widen track and source wider axle to accomodate breadth of bike
  • side-swing tailgate -- mounts to reinforced bedside (as oppossed to drop-down gate)
  • add your favorite canopy for wet-weather protection -- build a vintage custom like Scott Sensing\'s or...

  • Bumper? side-swing (like tailgate) or drop down (think original tailgate setup with a bearclaw latch or somethin')

Or... Have a look at this. Personally, I wouldn't dream of towing a nice looking motorcycle without a shield built onto the trailer to protect the bike from debris.
Or... Unloading\'s a breeze with one of these!
