Here's my take on this idea of width, regarding towing it. It's mostly what you get used to. Both my horse trailers are the full legal width ( 102" at the wheelwell/fenders ). One of these trailers is what my 18 year old granddaughter learned to tow with. One day recently, I followed her in the other truck and trailer to a barn 60 miles away. Not once did she place a wheel wrong, even on the narrow-ish county roads. To her, this is the "normal" width. I never told her some are narrower than others. All in what you get used to ?
