I had a major power lost on my diesel motorhome when I was on my way back home to Canada, following a emergency call to them the team of Mars Diesel Inc. Took care of me quickly by giving me the diagnostic of the problem cause, replacing the faulty parts and in really short time for the job to accomplish, at a competitive price. I want to thank all the team and the owner John which took care of us all along the repairs time and with smile and friendship. Thank you so much for your help . I recommend Mars Diesel Inc.
