I store mine like this and live in Santee, nuff said these things are tanks, I've noticed the slightest indentation( very small ) where the kayak rest on the hanger. This is obviously not my Outback but I do store mine here!
I got the hangers from Home Depot, used lags into the studs, reinforced the hangers with 2x4 cut to fit the wall as supports in absence, back all at a 90' angle to give leverage on the bottom part of the hanger! Very very sturdy and wife can still pull her Jeep Cherokee in with no problem!
