Actually, I said 8 months.

Mine is used 12 months out of the year. It's still hot in Texas and in many other states in the winter months and cold in the morning in Colorado and other states in the summer time.

I have 2000 hours on my unit. If I would have idled that much at $4.50 per gallon it would have cost me $9000 plus the wear on my engine.
While I'm sure you likely do use it 12 months of the year, that isn't the point. The point is, if you didn't have the APU, would you idle every single night? I know I don't. If it is under 70 degrees and over 30 degrees, I don't idle. I know for a fact that when you first bought the truck, you weren't idling during cold temps (I think you said somewhere around 30 degrees or so, if I remember correctly). That is a night that you would have used no fuel without the APU, but with the APU, you are using fuel.

This is the discussion that needs to take place. Thats why it's good to have this here, Fuel is only going to go up and more idleing restrictions will follow,...so lets review.
1.Steve bought a complete package he loves it but it doesn't cool as much as he likes, and the genhead burned out in less than 2000 hrs.

2.Rev when to the other end of the spectrum and almost had his own Burning Man event and no APU.

3.I went in the middle and have had nothing but problems, and if I couldn't weld,do electrical,and have more than average mechanical skills,....I would be money/time spent and no APU.

4.Heavy has a monster 8,000 watt quiet unit that has run great for years.

Take your pick,.....

There are a lot of variables there. Cost, size, needs, etc. If I could fit Heavy Duty's 8000 Watt beast on my truck, I probably would. Unfortunately, I don't think I have the rail space for something like that (since he has a big bunk and I don't).

But if I had to choose (and it appears I do), I'd go with the straight-up generator, manufactured by someone who has been in the business of making them far longer than the APU manufacturers.

I dod not buy them so I can't coment on that but the last two trucks I have run both had Thermo King Tri packs on them and they work great in my opinion.

The both keep the truck comfortable at night in the heat or the cold that we get up here and the generator fuction sees to do its job at keeping the batteries charged up. They were both plumbed into the trucks cooling system to keep the engine warm in the winter also.

This last truck also have a power inverter to go with the Tripac which is also a plus for me since it is large enough to run a Microwave or a George Foreman grill and a Refridgerator.

A generator supplies 110V power to the cab. An alternator charges the batteries. A TriPac doesn't have a generator (it uses an inverter for 110V power), which IMHO, is one of the drawbacks.

Ya, but did your unit start on fire or the head fly off? Was it really worth spending all that money when you could have built one yourself for a fraction of the cost. Sure, you can go to sleep at night not worrying about being burned alive but is that worth the extra money you spent? You just push a button and everything turns on and off and works. Is THAT really worth the extra money??? You don't have to fix anything or diagnose why something doesn't work just right but is THAT worth the extra money.

Sure, just sit back and push a button and download your porn. Real men build their own and risk all the consequences and work on improving what they have built. You specialized carriers suck, your all lazy. I'm sure it must be quit an effort to push that button. I wouldn't be surprised if you had a clapper hooked up to it!

notsteve I want you to know that I just can't reach up and push a button to start mine, the control is in the cabinet under the sink, I have to ether set up in bed or pull my leg out from under the covers and use my toe to start or stop the generator. Thanks for the clapper idea, I'll get started on that real soon. But since I am old and have to get up at night and take that long 2 step walk to the bathroom maybe it wont be necessary.

You mean you've never had anything break on your APU, and you've never had to diagnose why something wasn't working the way it should?

Uh huh. Suuuure. I think Steve's selective memory is in overdrive.

This unit is only $7500 installed(no tax) in a stainless steel box, should give 30000 hours of service easy, another $1000 for roof mount AC and a few more goodies and you have a GOOD APU that works every time. They have been doing this for years so they know what works.

Everytime I run mine I have to find out why it's not working properly :lol:


Heavy, that genset is a good one, I agree , I have seen that unit in high end RV's, so they must be doing it right. The price is decent also. Maybe a 3cyl/1800 rpm unit is the way to go.
