About
A company built around real work
MSD-USA LLC owns and manages companies that build software and keep diesel-powered equipment running — and the services that support both.
What we are
MSD USA is a holding and management company. Rather than a single product, we own and operate a focused group of companies across diesel service and software development.
Our role is to provide the backing, structure, and shared operational support that lets each company do its best work — while staying close enough to the trades and transportation industries to understand them firsthand.
The sectors we operate in
RV & Motorhome Service
OEM-certified mobile service for RVs, motorhomes, coaches, campers, and travel trailers — brought to your campsite, home, or storage. From engines and electrical to AC, plumbing, slide-outs, and roofs, our technicians cover all makes and models with 24/7 emergency response.
Commercial Truck & Fleet
Mobile, on-site diesel service for 18-wheelers, commercial trucks, and motor homes — emergency and scheduled repair that comes to the vehicle, so drivers and fleets spend less time off the road.
Marine Diesel
Service, repower, and maintenance for marine diesel engines and systems — from yachts to working vessels.
Power Generation & Stationary Diesel
Installation, service, and maintenance of power generation and large stationary diesel systems that keep facilities running when it matters most.
Industrial & Heavy Equipment
Maintenance and repair for industrial and heavy equipment — keeping demanding operations productive, safe, and on schedule.
Software Development
Product engineering and custom software for companies in the trades and transportation — built by a team that knows the work firsthand.
