TennMan and beyond !

OK. So It will keep main engine warm on cold nights. Good.
I'm guessing the switch in the box would be turned on all the time. This will keep the batteries charged and the coolant warm. The switch in the bunk is for climate control only?
I'm thinking one would then turn the main switch in the box "off" when on home time (normally) and "on" when on the road.
When the truck ignition is turned on the system will stay off?

 

Yup..your set up is different than mine.
I have the switch on the dash..turns tripak on/off.
Then climate control in sleeper.

Arctic package is nice..no hard starts when it's a might chilly.

 

Thanks to you both. I now have the Park Smart. Not very happy with it. Cooling and heating duct points at my head in the bunk also, toward the rear instead of forward. Front of cab stays hot.
In the winter, the bottom bunk is cold and the top bunk is hot.
My heater went out and I'm having a lot of trouble finding a dealer that is willing or able to fix it.
It siphons power from the truck batteries, and my TV and cooler shut down pretty quick. Well, about 11 more weeks to go. counting the days.

 

Okay, apparently my tri-pac is different from yours. I have a tier 2 and that's how the artic package is.

 

where is that?

 

Laredo trailer inspection station. Makes sure the lights get replaced after crossing.

See that one on the right? They stole the tandems!!!!

 

It ain't hell, but you can sure see it from there lol

 

Now, now, you can't see it from there. There's an expressway and some buildings blocking the view.
