How much is too much for a used APU?

It all depends on the condition. Check the oil, if it is dark, this means the unit needs a service. Every 1000 hours you have to change oil, oil filter, 2 fuel filters and air filter. Use synthetic oil 5W40 for diesel. Check the alternator, the ac and the heather. If you don't know how, go to the nearest THERMO KING CENTER and pay them to test everything.

These are good units if you take care of them, friend of mine has one with over 15 000 hours, still working good.

 

$10 is too much for a apu in my book. Onan diesel gen~set and roof air is the route I went. Works awesme and its a stand alone system. I like having my storage space under the bunk..... Oh, did I mention it was cheaper?

 

I had a tripac with 14,000 hours. Off the top of my head I don't think I've seen a used one less than $4K. $3K isn't bad if it's in good shape. People sell stuff for a reason. What was that reason?


Onan is good for a RV. They are not known for the high hours that a tripac is. 4000 hours on a RV and they think it's wore out.

 

Good enough for ICT good enough for me. I love mine. But, different strokes for different folks.

 

TK's and Carrier's in the truck paper all the time starting at $2500 with variable hours. Some give warranty.

 

i would strongly advise, if you are getting a used APU, take it to Thermo-King have them do a complete workover, finding anything and everything wrong and fixing it (they will give you a guarantee on their work)

same with buying a used reefer

 

Thermo king dealer in Joplin was selling used units for 2500 a few months ago.

 

I like the idea a lot but why not get the apu and use its generator to power the roof mount?

 

The generator is not strong enough to run an rv style roof air. The little generator will power it easily and then some. Its also a stand alone system meaning the only thing it shares with the truck is a fuel scource. Its not as loud as a clunky old TK. What CondoCruiser said is true, they're not rated for as long as a regular apu but oh well. What I can tell you is that when my A/C compressor went down and leaked all the 134a my truck stayed nice and cool. You see plenty of people hauling around a cheap gasoline generator on their catwalk to power a window a/c they stuffed in the back of the sleeper.... this is just a more elaborate setup.
