Cornerstone Mobile Service

Keeping Your Commercial Trucks On The Road

Cornerstone Mobile Service is a subsidiary of RMQ Inc, where we manage our own fleet that runs 24 hours, 7 days a week. After implementing our own preventive-maintenance programs and being pro-active instead of re-active, we found our cost started to decrease considerably. We started to minimize the unknown and we quickly became in charge of our fleet vs our fleet controlling our profits.  ​
We believe this resonates with other fleet owners, so we launched Cornerstone Mobile Service and it has been a huge success! We have seen our customers run more profitable and efficiently than they did in the past.

Customer Testimonials

They are by far the Best service company in the Twin Cities. They are priced way less than a normal repair shop and treat you like family. Corey is extremely honest and looks over the entire truck for you while he’s there and will let you know what absolutely needs attention today and what might need attention in the near future. The best part about them is that they will almost fix anything for you on the side of the road or in a parking lot and they come to you. They do absolutely everything in their power to avoid a tow bill. They are the only ones I’ll be calling when I have emergent issues and just basic maintenance.
