Howdy and what picky some places can be! Industry standards for arrival at refrigerator trailers is 3/4. That will provide about 3 days of fuel to run the reefer unit. We arrived with 7/8 tank and were refused entry to the delivery until we got fuel and returned with a full topped off tank. Guess what? That was 15 miles each way added on for fuel then we ran into heavy traffic due to construction. We aren’t even dropping this trailer since we are a live unload. Total waste of time.
