There is a lot of wisdom in TJs post. I can not say for sure what I will do as my KItFox is still in the rebuild stage. I have my hanger a half hour drive away but I could park an enclosed trailer 5 min down the road and fly from there. The question I am faced with is would I fly more with the plane close with the wings folded in a trailer or 25miles away and not have to fold the wings. One of the reasons I am rebuilding a Fox is to allow me the freedom to choose from a couple of options. As hanger rents increase I can build a trailer for less than a hanger and keeps my options open. I think if you only get to fly weekly then folding every time might make sense, but if you get to fly daily then a hanger that allows you to pull it out and go might be the best option. The thing about the KitFox is it does allow you options. Something you don't get with most other planes.
I had a hanger that I had to use a dolly system to get the plane in and out and while it worked ok it was troublesome. I still got 100hrs a year in that hanger and I think wing folding might be less trouble.
