Now I Remember


When I first started trucking I didn't have an APU or Espar in my truck. I would get my Mr. Coffee ready the night before and hit the button with my big toe. Getting out of bed to start the truck when it was 10 degrees was painful.

It sure is nice to set the Espar to 50 when going to bed and not have to worry about the batteries or anything else. Yup, I'm spoiled for sure!
 
On the airtonic D2.

Sitting here listening to mine fire up, starts to heat nice, then like the fan starts to surge. Did that first winter I had the truck now it's doing it again.
 
Had 2 fans go out. Probably the same 2 year time frame. The fan is one thing that doesn't give a code back when it fails. A typical fan failure is when the unit is running fine then all of a sudden it stops dead with no normal shutdown or anything, just dead stop.
 
Replaced the entire unit in Jan 2013. Last year Feb 2013, burn chamber. Pretty that was fuel related to what was happening.

Now the u it is acting same as it did Jan 2012.

Need a computer to plug into the u it to read hours etc. It is supposed to have a 2 year/ 2000 hour warranty on the fan.
 
I should start up a business rebuilding them when I retire. I think Thermo King and all the other places are charging a ridiculous price. Most fix your unit for what it costs to buy a brand new head off Ebay
 
I just never could run the numbers to get to where an APU would give a decent ROI for me. I stay up north all year, so summer is not a big issue. Maybe a few days I need A/C to sleep. Winter, a bunk heater does the trick most of the time. To keep batteries up and engine warm, I just use a Yamaha EF2000is sitting in a box, mounted on the frame rail It will keep batteries up via the Xantrex inverter charger I have under the bunk, and run an oil pan heater for the engine and do it for 10 hrs on 1 gallon of gas. And I can even use the generator around my property for any off the grid needs, or camping. Was -13F the other night in MI and all I did was run the bunk heater and the generator which kept batteries up, handled my power needs in the sleeper, and heated the oil in the oil pan which also warmed the lower part of the engine. 1 gallon of gas for the entire night and truck started just fine in the morning.

I can run the thing, stand outside in front of the truck, with trucks beside me running APU's, and I cannot even hear mine running. Even in my cab or sleeper, all I hear is those stupid APU's. I have to look at the Xantrex to see that it is receiving AC power to make sure the generator is running, unless I physically go out and check it. The generator runs in an enclosed box on the rail with a couple of vent ports for it. Nice and secure and out of the weather.

Total weight of the generator and box... 60 lb. Total cost of the whole setup... $1000. That is for box, generator, and oil pan heater. Webasto bunk heater was factory installed. And the generator is easier and cheaper to maintain, and far more versatile than any APU could ever be. But if someone can justify buying a full blown APU, then go for it.

that's all you really need is a small genset and a portable AC vent the hose out the window. a you can get a space heater also for winter. and if you get a large enough genset you can even run high drain devices all together like coffee makers frying pans ect ect. I can't see justifying the cost of an APU unit!! a genset in an enclosed box is all you really need. I love my EU7000IS it's quiet and easy to sleep with if I had to. it's even quieter than my friends 2000 watt honda

I think I'm probably the only person that can, and it relates directly to my niche, and I'm sure the ROI is long, long into the APU being on the truck which is now at 876,000.

My truck is an 06, bought in 07. The APU (Rigmaster) was installed shortly thereafter. I do use it a lot, and for several things. I use it to power a block heater, for climate control in the truck, and (the niche part) keeping batteries charged on some of our steerable trailers when the truck has to sit under a load for a few days in cold weather. I'll run extension cords back to battery chargers all the way at the back of the load.

It gets more complex from there but I'll stop now.

Because usually if I'm parked for 3 days or more, with a trailer that long, I'm headed to a hotel too....LMAO.

I did talk to one of our owner operators too, whose a one man one truck operation and he said he's run the numbers a billion ways and can't seem to justify one either, and gets along just fine with an Espar and a 2500 watt inverter.

Are you using the trucks factory ac on those hot nights or do you have something else?
