Can You Install an APU on a Pickup Truck?

Installing an APU (auxiliary power unit) on a pickup truck can be a great way to save money on fuel and emissions costs. An APU is a device that provides auxiliary power to the vehicle, usually by using an engine or electric generator.

It is an efficient way to keep the cabin of the vehicle warm or cool while it is parked, and can also provide other services such as running an air conditioner or charging batteries. However, installing an APU on a pickup truck is not as straightforward as it may seem.

First of all, it is important to assess the size and weight of the pickup truck. Many APUs are designed for larger vehicles such as vans or RVs, and may not be suitable for smaller trucks.

Additionally, installation requires expertise in electrical work, so it may be necessary to hire a professional to do the job properly. Furthermore, some states have regulations regarding the installation of APUs in vehicles.

The cost of installing an APU on a pickup truck will vary depending on several factors including size, weight, type of APU and the complexity of the installation process. In most cases it will cost several thousand dollars for all components and labor involved in the installation process. Additionally, there may be additional costs such as permits or insurance if required by law.

It is also important to consider how often the pickup truck will be used with an APU installed. If it is going to be used rarely then it may not be worth investing in one at all. On the other hand, if it will be used frequently then investing in an APU could pay for itself over time due to fuel savings.


In conclusion, installing an APU on a pickup truck can have many benefits but there are also many considerations that need to be taken into account before doing so. The cost involved can make it prohibitively expensive for some people, but if used frequently then it could pay for itself over time due to fuel savings.
