Auxiliary Power Unit Weight Exemption Guide

Auxiliary Power Units - Weight Exemption Guide

When it comes to fuel savings, Auxiliary Power Units (APU) are a big help. By eliminating the need to idle while parked drivers get more that 80% reduction in non-driving fuel consumption. Yet you can still enjoy all the benefits of your truck’s comfort systems. Installing APU is a quick and easy way to add some extra longevity to your fuel tanks and help you stay compliant with anti-idling laws.

However, they do have a downside.

They are HEAVY.

Adding one of these bad boys to your truck will come with an additional 400lbs. For driver’s who haul close to the weight limit already, this is a big deal.

The good news is that most states have now passed exemptions to allow for the additional weight. Unfortunately, since it is up to the State to decide, those exemptions are not all the same from one border to the next. So if you are using an APU, then it is important to be familiar with the laws of the States you typically travel through and plan your routes accordingly.

Take a look at this graph from the Track Your Truck blog. With a quick glance, you can see which states have exceptions and how much weight they allow.
