I have the maintenance logs for this bus. The last thing that needed to be repaired that wasn't, was seats and a dead battery.
The AC was topped up with 1 lb of freon and a new belt in August 2019 and it was only driven about 1000 miles after that, and was parked in November 2019 after it had the brake valve replaced. As far as I can tell, it was never driven after that repair, the engine compartment light was left on and the brand new batteries installed in July 2019 were drained stone dead. The light was still on and the batteries still shiny when I showed up in May 2021. I put in new batteries, it fired right up and I drove it 1000 miles home with no issues.
Prior to that, it was given a full charge in April 2019 and passed a leak test, and previous to that, a full charge with a new expansion valve in August 2018, for which there are several entries as they didn't seem to immediately figure out that there was an expansion valve bad.
It was given 4 lbs in November 2017.
4 lbs in March of 2017.
12 lbs September 2016.
2 lbs in February 2016.
Seems like it does leak a little, but most of the problems they had were with the expansion valve in the middle unit. Seems like they didn't catch that for two years or more.
