Last night I reread the instructions. Imagine that ! There is a card-stock shim that is to be used with "O" gauge track. It raises the loader building by about 3/32". It did help but no more than four milk cans can be loaded into the reefer, by the loader. Any more than that and I think what happens is that the cans push one another over in the reefer as they bunch up.
I think I may remove the body of the reefer and watch as they are loaded by the auto loader, to see exactly what is happening.
The auto loader in an ingenious accessory, as is the K-Line milk car. However, depending on the track layout, one cannot see the cans being pushed into the reefer, in most cases. I could relocate the loader so that the reefer would have it's loading doors facing me. It would still be within reach if something went awry.
