Yes it makes a difference but, it depends upon how you travel. For me, traveling back roads and often gravel roads, width makes a big difference on tight turns and in tight spaces. For me, towing with a HD F150 I wouldn't want the extra weight. For me on a limited budget, the extra square footage of air resistance and impact on gas mileage makes a big difference over long distances. For others who travel interstates and main highways and are satisfied with the other small sacrifices of the extra size, perhaps they would see no issue.
