APU's VS. Do It Yourself

I don't have room for a conventional apu so I was looking at putting a small yanmar 3cyl diesel and generator head in the passenger side toolbox of my Kenworth.

I just found out about kohler power systems units. Compact single cylinder units with ac compressor and alternator setup.

And they would fit on my truck.

 

here is my setup. rv generator with remote start , roof a/c & heat , 13 gallon gas tank. 2200.00 awesome

 

battery charger in sidebox. homemade shore power. charges off the 120 volt side either of the generator or the wall.

 

don't APU Run Off the deisel ?

 

Gas RV gensets burn about a gallon an hour. Idling a big bore diesel burns about a gallon an hour. Where is your savings? (assuming your rv genset isn't diesel)

 

Unfortunately there s no real way to mount this on a condo

Most of them do. There is one now that is propane. I am designing a hybrid battery/propane unit for my truck. more info here http://www.thetruckersreport.com/tr...wheelers/82129-increased-milage-apu-idea.html

 

why did you mount the roof unit backwards?

 

only the big genies run that much fuel. there are allot of smaller more fuel efficient units.
plus your saving on the wear and tear on your motor. And if you have an EGR motor that is a considerable amount since 0 idle time is what keeps an egr motor running good

 

That's great! Where did you get it?

 

My idea... portable ac from walmart with a low btu rating >.> 300-400 bucks, Energystar versions pull around 600-900 watts, plug into inverter, exhause out the window, boom ac is done. Weighs between 20-60lbs, about the size of a small fridge.
