Timeline & Feedback

Date: 4/26/2024
Driver Feedback:
" It was the first night I tired to use it in SE Arkansas, it had gotten up to about 80+ degrees during the day... Somehow the remote changed the reading from F to Celsius and I couldn't figure out how to flip it, so I just went with a Ceelsius temp of 21 and turned it on. No air was coming out of the driver's side port below the bed and it just didn't seems to be cooling off at all, so I just shut it off and said I would deal with it Saturday night. I was too tired to read the manual, but I knew both ports were blowing out cool and strong air at the shop."

Driver Feedback:
" Parked up a new load at our terminal, made it to eastern Arkansas when I shut it down that evening... Again it got up into about 80 when I stopped... Raised the bed and found one of the air ports was disconnected, the plastic next was still clamped to the air duct hose. I just had to snap it into the unit good, probably wasn't when they swapped the units. Thru the manual I figured out how to change it to Fahrenheit and sync the remote to the control box. Set that baby to 66 degrees and the 2nd lowest fan speed, did not close any curtains in the truck... Woke up during the night and had to shut it off, the Idle Smart (which was left off) was showing the cabin temp at 64 and was 79 when I went to bed... It worked great!!!

1. Cools great so far in mild temps
2. Can really crank out some air
3. Hardly any noise

1. The remote and inside controller have strange icons for the functions
2. The manual sucks"

Driver Feedback:
" Until the sun goes down it naturally needs assistance from the truck A/C system but that was to be expected... It's just great they can operate together unlike a traditional diesel APU"

Fleet Manager Feedback:
"Driver is running the Polar Fox APU while driving to keep the bunk cool. And this truck's fuel economy is almost of the highest in the fleet"
