ORV trailers are the "basic" 8ft width, which doesn't include any added awnings or slide toppers. The length that ORV quotes is overall length, includes tongue and ladder. Arctic Fox does make a line of 8.5ft trailers, ORV does not at this time.
Since it is not a "lite" model, I would suspect that is every bit of 8.5Ft wide plus some extra for wheel skirts to put it at least about 102" to perhaps 108"..
