Vinsky, sorry I can't help you on the Triumph question but I do have a short video of Marlo about to make a pass at (I believe) Scapoose Drag Strip with that Thrust Dragster.
As with most of us Salt Freak's, Marlo's career started with Drag Racing and I believe he ran the twin Triumph at local strip's.
As far as spare part's, Marlo has a "parts trailer to carry spare parts and support equipment.
Unless he gets a much larger tow rig, I think that with a 53' steel trailer, the Streamliner, and Car Carrier, Oz's F-350 is probably about maxed out.
Amongst the spare parts are replaceable carbon fiber wheel fairings (using molds taken from Jim Humes hand crafted Alluminum originals).
The reason? A flat tire will destroy its fairing but hopefully nothing more........ hmmm, maybe they could add automaticly deploying ski's............... hmmm......... let's see, their has to be room somewhere's.......... hmmm.......... Nope, it's all pretty much filled.
After all, it's only forty two feet long.......... Bob

Trent, what humor? I only state facts from my memory or at least thats what I remember.
