No idea about this, any old hands have ideas?

Your company needs to worry about that, I believe.
I never had a problem, even in a reefer-never turned it on.

 

Share a case with CARB....what else?

 

Hey im here to help on keeping the beer from not freezing. Just let me in the back an ill keep a very VERY good on them. Your trucker buddy Miles

 

I had an issue like that with water over Christmas.
Called and asked dispatch. My weather forcast had it 15 degrees one night, otherwise over freezing.
He had me run the truck all night while I was home, then I went down Christmas day and shut it off.
I had not issue on delivery, I guess the vibrations helped.
This was not the first time eather lol.
I am just glad of a reason for my company telling me to keep it running.

 

yeah we haul beer as well, they tell to to idle the truck, move the truck ever few hours, ( just rock it ), by one of those propane heaters and put inside...* with the door cracked a bit * or if were at one of our terms to pull it inside the shop or back it into a dock to keep some heat on it..

 

I really doubt a propane heater would be effective , especially cracking the door in weather that cold .
But that reminds we I was getting a haircut this week and one of the stylists received a few boxes of supplies . She said "Hey , one of these boxes says freezable " Another one replied . "I wonder what's in there we'd want to freeze "

 

Step 1 - Take the ticket
Step 2 - Wipe you butt with it
Step 3 - Hand it to the officer
Step 4 - wait for the officer throws it down in disgust and call his duty officer to let them know you saw the officer littering.
