APU. Noise and fumes.

APU is for driver comfort, the ability to keep a fridge running all the time without worrying about battery drain, sleeping in the summer in states that don't allow idling, and yes, saving money.
You really think it's not hard on a motor to idle all the time? Especially with dpf equipment?
APU burns 1/5 of the fuel, so even with cheap fuel prices a guy can save an extra 15-20$ a night worth of diesel. So even being home 2 nights a week could still potentially save 3-5k a year. Even with the limited maintenance required of a tripac that's a 3 year return on investment. Even quicker return when you calculate in being able to push out oil changes a bit of the truck engine, and even faster return when fuel prices inevitably go back up.

 

Is Wabasco a milder version of Tabasco? lol

 

I understand. I was pulling a noisy reefer one time, so parked wayout in the open away from other trucks. Some flatbed guy parked right next to me, then asked me to turn the reefer unit off. I explained to him that I had refrigerated foods coming out of Florida, so can't turn the unit off. He still complained as he crawled back into his sleeper. Plenty of places to park, but he wanted right next to me.

 

Yes Sir. EPA from Dear old Uncle Sam.

Remember we considered those #### things too fancy and never used them in our day. Just set the rpm to 1200 and went to bed. Cheaper than a hotel bill.

If I ever wanted a APU on the rig, it should provide house power 120 volt as well as maintain the engine block temperature in addition to heating and cooling off the same fuel (Desiel.)

I do understand those things are loud. I ran a Generac 12500 watt peak to feed my entire house in power outages but had enough acreage so that the sound field dissipated over 700 feet before reaching anyone. Our City brought in trailers with engines on them larger than our cars and trucks to pull water from the wells at the same time too. Shakes the ground they did.

 

I just noticed the guys beside me does sound like a 3.5 Briggs on a 20 inch cut mower. As hard as it died had to shake the truck. The carrier on the front of my reefer doesn't shake that bad

 

You would think they will build a patch cable to feed tractor with reefer unit. Win win.
