I can get some pictures of Nigel's rig this weekend - I might have to sneak around 'cause that pesky Brit can be a bit cagey sometimes!

He has an internal rack system that you load a cat on and hoist it up to the ceiling inside the trailer. You can then load a second cat underneath the first, a golf cart, or even a mini cooper. Cradles on the roof allow a third cat to go up top and all the masts go on the roof.
