Hmm. That's not a bad idea! Especially the reefer we are using is old. Where is the best place to put it? Right after the shoot?

Fitted correctly, it blocks off the chute as it's really a false wall and the front of it is all you are cooling. I just ran an ice cream load and it was nice. 2P4D and after my second drop, had less than 1/2 the trailer to cool. It's nice too when you back in with a load and doors open to put the bulkhead up to prevent sucking in all the moisture as well and constantly cycling for defrost.

I'll normally put a load lock up high even with the last pallet, slide the bulkhead in place and the put a load lock about in the middle holding the wall in place. Never had it come down yet.
