What is the Best APU for Semi Trucks? 6 Important Things to Consider

Every trucker who has spent time on the road knows it’s not an easy job. Making life as comfortable as possible is the key to success.

One of the greatest developments in the trucking industry over the past few decades has been the widespread use of Auxiliary Power Units or APUs.

Because today’s APUs are complicated machines and involve a considerable financial investment, it’s critical you choose the right one for your specific needs.

In this blog, let’s take a look at 6 key factors for you to consider when choosing an Auxiliary Power Unit for your truck.

Product Quality

One of the most important factors to think about when choosing an APU is product quality. You’ll need to depend on your APU all year long, including during the blistering heat of summer, and the frigid temperatures of winter. For truckers, an APU failure is not an option.

Make sure the unit you purchase is made from top-quality parts and assembled in a modern production facility. When it comes to investing in an APU, quality is everything.


Before you decide on an APU, read up on the product’s dependability record. Does the unit you’re considering have a good history of being reliable? What do reviews say about it? Learn all you can about what other truckers think of the unit. For after all, what good is an APU if you can’t trust it to be dependable? Do your homework!

Parts Availability

Even the best APU units will need replacement parts from time to time. As you look for your next APU, find out how easy it is to get parts for it, should you need them.

Are parts available nationwide, or do they need to be ordered and shipped? There’s great peace of mind knowing that parts for your APU are available pretty much anywhere.

Fuel Efficiency

One of the many benefits of having an APU on board your rig is fuel savings. APUs provide all the electricity you need when not driving, so you don’t have to idle your engine all night. But when it comes to fuel economy, not all APUs are the same.

Some units are known for their frugal, fuel-sipping ways, while others not so much. Before you decide on a unit, be sure to check on how good it is at conserving fuel.


An APU is only as good as the company that stands behind it. As you take a look at different units in the marketplace, find out what kind of warranty is offered with them. This will be important information should you have any issues in the future.

Service Ease

In addition, how easy will it be to get your APU serviced? If you are an OTR trucker who drives coast to coast, this will be especially critical. Make life easier for yourself, not harder by picking an APU with a great warranty, and service network.
