I have a 8ft Hybrid Sullivans grooming chute. I love the chute due to it's strength, and lightness compared to the all steel chute. The only problem I have is that when we go to a show, I am the one that get's stuck moving it into and out of the stall. This can sometimes be a ways away from where we unload the trailer. Even though it has wheels in the front, the back needs to be carried by hand. I have seen where people mount wheels on the back as well to pull like a trailer. How are those mounted? Is it a partial cart that comes off while in use? Just curious as to the ideas that people have come up with to move these around. Any pictures would be awesome, but just ideas would be great also. TIA
