my husband built us one, it's like a camper shell, he custom fit it to the truck. i like it because we can look throught the window and see how they are doing, unlike the trailer. for hauling one or two long distances it's great - we had 2 yearlings and a weanling in it once and they still had plenty of room (long-bed truck). and especially hauling in a state where they have a lower speed limit for vehicles with trailers, it saves us a lot of time. we don't have dividers but i watch constantly and have seen no issues with turning corners, braking or increasing speed. the pics are at home so i will edit later and post what we have. to me it looks like the Beverly Hillbillies, but hey it works!!
as for loading, the two of us can scoop up a mini and pop them in... if we don't have a porch or hill to back up to. we've unloaded them the same way but it's harder because they try to "help" by jumping, you have to have a good hold on them and not mind being kicked (not hard, just them trying to jump). i much prefer backing up to a hill!! but we have never had one hurt loading, riding or unloading.
