One of the joys of being an RVer is ... We think differently.
I volunteer at a thrift store. In order to handle both incoming donations and to process groceries for a food giveaway they had a storage building put up.. Roof opening is a bit low though, an even six feet (As I age I'm shrinking, I'm down to '6'2" so you can perhaps see a problem here.. "The boss" is also about my height..
I can tell you those 2x4's hurt
I took a couple of noodles and a 1x1 and slipped the noodles over the board.
A pair of lag bolts puts the bottom of the noodle at about 5'11"
Now.. that's just low enough I see it and duck.. but the boss says it works real good
The store I bought the noodles at.. Well the clerk and her 6"+ Hubby have a storage barn too... (Idea copied)
