We used GS about three weeks ago, out in rural southwestern Missouri to replace two blowouts. Wait was 90 minutes or so, and they eventually got the job done. We were more than a bit surprised when a guy with an old pickup showed up to do the job. Dismounted/mounted two tires on our fifth wheel rims BY HAND using tire irons and other hand tools. It was pitch dark out and he only had a little light on the side of his truck to help caution other drivers. Very scary situation, however I have to say his skills were pretty impressive, and you couldn't ask for a nicer guy. Still wonder if this is a "typical" scenario though.
