Does an extra 6 inches matter?

...get your mind out of the gutter..... Am talking about the areodynamics and towing characteristics of a 7.5 foot compared to an 8 foot wide. With things equal like frontal shape and height would there be much of a difference? Just a few inches more to stick outside the tow vehicle. It was a conversation we had earlier....just curious.

It definitely matters in the gutter and if you are talking about a 30 foot long trailer, it means 15 additional square feet which you will notice. I would think the aerodynamics would be less important than the fact that that extra 6 inches makes the rig about 8% larger, and probably about 8% heavier, not insignificant. Personally, I would go with the larger, because square footage is always at a premium in an RV.
