I would say a BIG NO to air
freshener .
Our body will have negative impact due to long hours of
inhaling chemical "air" .
Mine cab will have natural PVC leather smells , not those Glades
freshener things like that .
I smell those china made one , 1 for $1 type , i smell liao
giddy .
To keep our body healthy , if no passengers , wind down window
for fresh air will be good .
Day shift very unlikely if weather too hot .
Only night shift can do it , even more cooling .
