No, nothing with a tandem-axle setup -- the largest were straight-chassis 6-wheelers. Largest stuff was Fire Apparatus: 1800 gallon tanker, pumpers, ladders, rescue, Medium-Duty ambulance box (Freightliner) -- mostly an easy driving E-350 Ambulance conversion.

duals have less tire on the road, so youd be adding MORE tire to the road with a large wide setup..

Multiple studies (including those of the EPA), prove otherwise. The Green Car Congress thread has a link in the story to the study mentioned and likely other studies for more info.

with a large wide single the back end of the truck feels too loose and gummy,
its a looks thing and you wont see it too oftin because its dangerious when hauling. I had to drive one and it was not a pleasent feeling..

Good info to know. I do see them more on trailers, which makes sense from the stability standpoint. I can appreciate the gummy feeling -- the company once ordered new tires for the E-350's, with too weak of a sidewall. The back-end was really yawing in level driving -- had to take them back. Not good on high-performance/response cornering either.
