Is this what you are referring to? The ultra-wide design of the DuraPlate trailer provides an interior width of 101-1/2" (scuff-to-scuff) http://www.wabashnational.com/DryFreightVans.htm
If I remember right Hyundia (sp) made some extra wide trailers that actually had a 102" width. These trailers were pure ans simple mistakes. I think this happened about 2-3 years ago and the trailers were going dirty cheap brand new because they would need a permit everywhere they go.
I just didn't want to run my mouth to these guys without knowing for sure that it didn't exist, but I will know next time. Thanks for all the replies!
