About two years ago i was traveling back from a horse show, when a trailer tire let go. Late August in the mid south, it was around 95 and very humid. My trailer is very heavy, (8 tons, empty) and I use 14 ply tires. I have a 36 inch breaker bar that travels with me, but muscling that tire off, on the side of the road, was exhausting. I bought a cheapo 1/2 inch drive impact gun from Harbor Freight the next day. I charge it the day before I travel and put it in the truck. It has been the best $300 I have spent in the last decade. I haven't had to break lug nuts loose with a four way, a cheater bar or a breaker bar since. Can't believe how much easier life has become with this tool.
