North America’s largest single-source provider of Service Trucks

Whether you like to call it a utility truck, service truck or even a utility service truck, it doesn’t really matter. What does matter is that you can rely on it 100%. Service trucks need to start every day, they need to function flawlessly when you’re doing your rounds, visiting your customers and travelling to far-flung sites wherever your skills are required. With this in mind, we sell, rent, service and maintain just two series of service trucks: Load King Voyager and IMT Dominator. We believe that the service trucks from these two industry-leading manufacturers are the very best you will find anywhere in North America today.

Are the utility service trucks for sale on your site really the best I can get?

Yes, we honestly believe they are and our customers do too. Companies in industries as diverse as forestry, oil and gas, rail and telecom rely on Load King and IMT trucks to get them where they need to be, day after day, week after week, month after month and year after year. And clients in the propane/refined fuel business are, of course, very keen on the Voyager P service truck, which has been designed and fitted out especially for their industry.

If you are looking for a new service truck that has an outstanding reputation for reliability, durability and functionality, we recommend that you check out the Voyager and Dominator lines as soon as you have the chance. If you’d like more information about a specific model, please get in touch using the number provided.

What do I do if my service truck stops working?

We know how important it is for you to be able to rely on your truck completely, which is why we recommend our Load King Voyager and IMT Dominator series. However, even the strongest, most durable trucks may occasionally falter and it’s what happens next that determines if it’s just a minor hiccup in your day or a major catastrophe. When you buy a used or new service truck from us, you get much more than a vague promise: you also get access to the full range of maintenance and repair services that we provide in the USA and Canada. Our team of highly trained and experienced technicians are always here to help, both over the phone and in person if necessary.

I can’t find any new service trucks for sale that have everything I want: can you help me?

Yes, we can. We offer a full customization/modification service to our customers. Whether you’re looking for something special in a utilities service truck or you’d like a building supply/construction truck with features not normally available, we can make it happen. Our customization team has years of experience modifying vehicles for customers in many different industries and would be delighted to modify a utility truck (or a whole fleet if that’s what you need) to meet your specific requirements.

For more information about our customization service or to request a quotation for the modifications you have in mind, please get in touch with us. It will be our pleasure to build a utility service truck that does everything you want.
