$40K and I'm gonna do what they say can't be done

I never pre-cool, just a waste of money. By the time you open your doors and back in the box is back to outside temp. Unless they have a hard on for it then yes. You wont kill a product with it being out of range for 20 minutes lol, man i ran 16 hours with no reefer on a load of grapes when it crapped out on me in NM to amarillo, TX (had to wait for em to open). Grapes are one sensitive load, 34*F and if thats not what they are pulping within a 5* you're screwed.

 

I have the 86" studio with the rock hard couch, i love it though, i dont like soft mattress's. But the 63" Peterbilt sleeper has way more depth than a 72" KW, KW measures them from the cab door, its really 60". Pete sleeper is measured from the opening, KW measures their on the outside, i think the Pete has about 5" more depth than the 72" aero or even the 60" modular.

I still like my KW interior over the Pete, especially my 86".

 

I think it depends on the reciever as well. I worked in Frozen at Wal Mart and would unload the frozen / meat and dairy trucks from time to time. If they werent within a certain range, we couldn't take it. On the trailers with the different zones, we had a policy of checking each zone as well.

 

I'd pre cool for some things, like butter. I hated hauling butter and I pulled allot of it out of Atlanta. Most other places i'd stop a few blocks or miles away and turn it on if they wanted it cooled. I had one place that wanted it cooled and it wasn't running when I got there. they made me wait like 4 hours while it cooled before they put me in a door

 

Yeah some places suck, my SBIII will bring a empty box down from 85 to 35 in a matter of minutes.......... I stay away from anything 32* or colder.

 

well just before I turned our last unit in the door hinges were worn out and the doors sagged, the seal had en better days. Needless to say butter and ice cream were not a good thing, at least not for the back two pallets

 

Could've been a little low on freon too, was the chute attached to the front with no gaps? My door seals are shot, but if i set it at 34*F it will read 33.9*F in the back.

I always raise the rpms in the summer time to 1550-1600rpm in low speed, in winter i set it to 1350-1400. That helps alot.

 

chute was attached in front. the rear few feet had ben riped down and I hadn't gotten it fixed. the biggest thing was the hinges. they were so worn that eventually when I got around to it I had to put three thick washers on the pin to push the door back up. Before I fixed it you could see daylight at top from inside..
I didn't care much. 80% of what I was hauling was slush packed collards which we actually heated to melt the ice off. That and potatoes were my bread n butter. But ocassionally we loaded other stuff,mainly when the west coast rates were up and we were trying to get out there

 

That almost sounds like the peanut butter plant in lLittle Rock. I like driving by there.
