Home made APU

[jorden486]

I've put 4 of these on and so far the results are fantastic.
Honda 2000i generator with BERGS extended run tank
10 amp battery charger
Small electric space heater
Home single room stand up A/C unit
My trucks are gone for 5 days and 4 nights and have never run the extended tank out-close in the summer months(running MT to S Cal only) because the A/C really draws the juice.
I also built hydraulic pumps so I didn't need a PTO. I hate idling. I built my own catwalk too. It has chain hangers underneath on one side and a square that generator sits in with a chain to lock it.
I tried a 3000 watt but couldn't get the extra fuel tank to work reliably. My drivers love them. They hardly hear them inside the truck and they have power to run extra household things.

The A/C unit requires cutting a hole in the floor in the sleeper-
