I have a lot of money in to this truck to make it run correctly, make NO smoke and get 22 mpg with my camper at times, 17 overall, so when it started acting up and i was new here i discovered them as my son had work done there. Anyway, when they called my with the diagnosis and the remedy they offered we both laughed. it was simple a hose had come off. They charged my for less than an hour i was both pleased and ok financially . That’s honest work I will use them exclusively .
