Is it worth it to get an APU (Auxilary Power Unit)

It’s not just about Deisel, but engine oil, and life of engine. If you do have the money on a new apu go for it, they are cost a arm and leg, and also repairs on a apu is expensive

 

And it depends where you are. If you mostly work in cold / medium temperature climates I would suggest just getting a Webasco engine and bunk heater.

If you need AC then an APU is more ideal.

 

I know two OOs that have APUs. One has had his now for close to five years. The other has had his for about two years. When we get on these subjects there are so many variables it's difficult to say with precision what the numbers are. I hear the break-even point is between three and eight years. There are some tax deductions available, and one of the people I just spoke of told me several times they was able to get a grant to help defray the cost of the purchase and installation of the APU. Another thing that makes an APU an attractive option is some of the anti-idling laws around the country. One last point. I think this thread should be moved to the OO forum because it's really OOs that are faced with these decisions. A company driver is not in that.

 

1) Yes.

2) Absolutely.

3) Without question.

You will also save thousands, tens of thousands of idle hours on your engine and after treatment system.

 

Depends on the truck and what you do with it, but for the most part I only idle for ac and use a espar bunk heater in the winter, idle about half an hour- hour before bed to recharge batteries or to use microwave and that’s it

 

Very true on the repairs. It also depends on the type of APU. I've had a couple of different brands and I'd go with the Tripac Evolution over any of them. Very reliable APU but repairs can easily exceed 500 dollars for things like a fuel pump. Make sure to get regular maintenance on these things because it's easy to overlook if you're not paying attention.

I highly value my APU to such a level that if it breaks down, I shut down until it's fixed.. All of the idling hours that would put ware and tear on the trucks engine are transferred onto a smaller and easier to maintain engine. Also, WHEN you break down on a roadside, you can still run your APU for warmth or AC not to mention appliances like microwave, fridge, and computer, while you're waiting on a tow truck. I've had experiences where I waited on a tow truck for hours in 10 degree weather, and you better believe that having this little APU can be a lifesaver.

 

An APU is worth the investment.
Some will only point to the reduction in fuel use and the cost of maintenance on the unit as not cost effective.
This is short sightedness, the reduced wear on both the engine and, if equipped, emissions systems is worth a large sum of cash. The cost of basic maintenance on an APU is peanuts compared to having one set of emissions sensors replaced, or a DPF/SCR cleaned or replaced.

The newest electronic APU systems are quite good and run longer than past models. Generally are lower cost and easier to install as an aftermarket project. They are quiet, no engine running.

 

There are several places where you can get a reman, if you don't want new.

The cost savings is an absolute no brainer.

Figure 2000 hours a year not on your engine. That's staggering.
