ABC Kompuuter Mobile Photo Finish and Time Measuring Truck

Rolling Unit customer ABC Kompuuter needed a modern solution to replace an old bus that was retrofitted to measure race times. The bus had several disadvantages from insulation in extreme weather, costly maintenance, and outdated look and functionality. To bring ABC Kompuuter’s operation up to date, Rolling Unit’s custom shop worked to outfit the new vehicle with our unique insulation, ample space, extra workspaces, attractive look, along with additional customized rooms for rest and shower. This was all achievable for our client with the 3-in-1 Rolling Unit truck.

About Us

Rolling Unit, Inc is a subsidiary of MDSC Systems and was incorporated in January 2023 in Florida.

MDSC Systems historically produced heavy military and rescue grade expandable container solutions, but back in 2016 Estonia’s Cancer Fighting Association was on the lookout for a mobile cancer screening unit. Heavy medical trucks were too expensive for a local non-profit, so we all had to literally think outside of the box. Seeking to outfit the same quality, insulation, square-feet, and customizability as our heavy equipment, but without the price tag – MDSC was more than able to meet the association’s needs. Together we developed Rolling Unit as a lighter, more affordable version of our military container solutions. Thanks to the generosity of the Estonian people, we were able to source not one but two cancer screening units for our non-profit partners.

MDSC Systems specializes in designing and manufacturing mobile special purpose container/shelter solutions for military, first responders, and medical use.
