I would like to hear thoughts on "safely" getting my windows to my place without breaking them. Trail conditions will range from "good" to "challenging". Should I lay them flat, build a rack and stand them up, etc...? I will haul about 10 windows total with little time or extra budget to replace any that break. I will not be hauling all 10 at one time. Any pictures of successful methods would be greatly appreciated. Thanks in advance.
