We have a Tiffin motorhome with a Cummins diesel engine. The check engine light came on so we called to get it diagnosed at the closest Cummins service center in Ocala. They had a four week wait for an appointment and a 60 mile drive. I checked around using Google maps and Larry Smith's shop came up. The reviews looked good so we called and got right in. He had to get the right computer for our engine and then found the problem and fixed it. We are very pleased to have a local, competent and honest shop that seems to really care. We will be passing this information around the local motorhome crowd. - Larry P. (5 star review on Google)
