I'm looking at getting a hive carrier to help move my hives around. Would like to get your opinions on what you like and why, what sort of loads can they handle (two full deeps?), how easy they are to use, how easy they are to use to lift the hive into/out of a truck, and any other thoughts you'd like to offer. My immediate need is to move a hive to a truck, then to off at another location. Thanks.
