I went from an 8 foot wide to an 8 foot 6 inch wide camper. I've not noticed any difference at all. Except the new one is longer and naturally heavier since it also has slides and the old one (shorter by 4 feet and no slides) was not as heavy. No difference on the road though. I never done a comparison of the actual trailer frame to figure out if the wheels are actually farther apart between the two trailers. It's possible the same frame width may be the same, and the tires may be the same width, I do't know, never measured it, never thought about it until just right now. But I do know, as far as wind resistance, ... nada! Enjoy the larger camper!
