I was in the wilds of Maine fishing. I stopped to visit a friend. Upon attempting to depart I noticed a flat tire. He had a tarred driveway and the the jack couldn't be fitted under the axle to jack it up.He called someone who owned a commercial garage and the guy came and got it up and changed the tire. When I returned home I purchased a jack that could be used for a flat tire.I reported it to the GMC dealer but I don't see anything that corrects the issue
