Picking up a used reefer trailer ....

I can’t remember if it has a pretrip mode were it self checks sensors or not. @reeferwrencher

 

Seems like a lot of hours but honestly, not really your concern. It’s the carriers problem.

 

Yeah it ll have the advance micro so you can run through a pre trip. Run it on cool mode,see if the ball is up in the sight glass and all the other usual things, belts oil coolant. You probably already did that by now anyway but good luck.

 

Before you consider it, get it to a carrier dealer and have them look at it.

Have them check the charge, the oil in the compressor and the shuttle valves. Also check the control unit.

Pull a sample of oil for an oil analysis

 

I would hope that your company looked at the trailer before buying it. Would be pretty foolish for them to not inspect it first.

But, at least a good and really thorough pretrip. Tires, suspension, breaks, landing gear, doors, lights, air it up and listen for leaks, look at all the cross members underneath the trailer for damage, look inside for evidence of water leaks.

May seem silly, but might be good to take pics of existing damage so the company/seller can't say the damage wasn't there before you picked up the trailer.
