I don't put my planes in the garage because in the summer it can get to 130°F in there, So I'm limited to in house storage. I did make a rack out of PVC for my planes In the spare bedroom.
At one point I had about 15 planes, had to scale back, they eat up a lot of realestate. I am at about 6 now. But my surface vehicles filled that space up again. 🤣
