diesel generator

Apu costs $10000-14000 plus maintenance, parts. How many years does it makes to pay it back? If you idle your truck 24h 360days then maybe its worth to have an apu. I idle my truck only in summer about 60 days, thats about $1500 per year.
In winter time I use espar heater, which doesnt need apu, only uses battery to ignite it.
So the apu will take to pay off 7-8 years. After that couple years more that apu will be worn out and thrown away.
I park many time at truck stops when temperature is 60-65 deegrees and trucks still are idling or running their apu's.. I call this stupid .. or only company drivers can do that.
So having apu is probably comfort ..but not a way to save money.
