"Anchorage, Alaskan truck driver here.....Owner of "Cold Night Trucking of Alaska LLC"

My experience with this mechanic shop (mobile service) was top notch. I had an air leak, and I really couldn't figure out where it was coming from. Mr Dayton sent out one of his techs (Trevor) and he quickly found out the problem, (Leaky air bag) he then went and picked up a brand new airbag for me and installed it and it definitely fixed my problem. The price was what they quoted me, and from me calling around they were my cheapest shop. We all know cheap doesn't always mean a good thing, but these guys were great. Very honest, and they actually are willing to hold a conversation with you, while working, if you like to do small talk like myself LOL. I told the owner Dayton, that I would like to make them my main mechanic in that area as I go through that area and my three other trucks all the time from Alaska. The Alaska Highway, especially through Canada is nothing nice. Once again if you choose this mechanic shop, mobile service you will not be disappointed and they definitely will not cheat you. Worked on in Johnstown, Colorado."
