Just curious on the average cost of a trailer pm and a reefer pm and at what intervals they should be done. Thanks.

As far as a regular trailer pm, all you really need is a lube job. Just get it done when you do your tractor for an extra $10-15. Everything else, brakes, tires, air, etc. is just inspect and should be done daily anyway.

A reefer pm will run you somewhere around $150. Intervals are usually 1000-1500 hours depending on the manufacturer and year of your unit. I usually do one between 500-750 since I don't put tons of hours on and $150 is chump change.
