How cold should a unit go? Buying a reefer trailer very soon

Stevens does not use a 6 number system for the trailers and i can see the outlines of 6 digets on the chrome

 

I'd also use a fridge/freezer thermometer in the center of the trailer if you're going to run the unit to test for cooling capacity. As a general rule the temp readout on the display is more or less a good representation of the temp but I don't trust any used trailer salesmen to not figure out a way to jigger with the unit to make it read lower then reality if there is some mechanical problem with the unit. 15 feels a lot like 0 in a trailer with open doors

 

That is an old Stevens trailer. It has the 53" below the remote indicator panel and the two red stripes across the front. That is tape covering up the black stripes. The side panels have been replaced where the Stevens decals were and i can vaguely see the residue from the red stripe that runs from front to rear. It also has the intermodal rub rails along the bottom of the side gussets. The one up at the top have been removed. Since i can't see the rear doors but i'd guess it has diamond stamped stainless panels on the rear doors.

 

you can run a rig dig report on the trailer it costs about 35$ tell you accidents trailer ownership history(if they are still around) and roadside dot inspections

 

Well, I started out as a Buzzard so I was certain it was a Stevens trailer. This is a good thing as the equipment is very well maintained. That 1st 8 to 10ft does look like it has been replaced. The inside shows the joint. Also, the processor/computer could have been changed and may show less hours than the engine. At $4300 it's a good deal. At $14k, nope, use that $ towards a new unit.

 

Awesome investigating. The Trailmobile is a great trailer. I own a 1999.

 

Just keep in mind that reefer insulation degrades over time. I personally wouldn't buy a unit that couldn't pull down to -15 to -20 in a reasonable amount of time. If it can't then something is wrong.
