When I travel I put the lid , charcol holder thing, the water tray and base in 1 plastic garbage bag. The center section goes in a second bag by itself...If I was going to put it in a rack like you showed, Id put it in whole securing it with a few ratchet straps...
"I love my country, I love my guns, I love my family, I love the way it is now. And anybody that tries to change it, has to come through me. That should be all of our attitudes.
Cause this is America and a country boy is good enough for me, son."
