When we were changing our tire some one stated that Tommy had an 18volt impact wrench that they said really worked good. So the first thing I did when we got home was look on line at harbour freight and low and behold they had one for 40 dollars off for a price of 99.00....I raced down and got one, figuring if it did not work well I could return it. Well I used it to remove the spare and reinstall the regular tire and wow it did an awesome job. I hope I never have to use it again. At the campground I had to use a 4x6 along with my trailer aid to get the flat tire far enough off the ground to get it off the lugs. Yesterday I mounted that Trailer Aid on to a 2x6 . I think they were designed for 15" wheels.
