We have the larger Arrow and really love it. "Cloudsplitter" (I think it was) pointed me to the 'Hitchin' Posts' from Camping World, and they have made all the difference it getting hooked up in the morning, especially when I have to run solo. From what I see of the Cub in the brochure picture I'll bet they'd help you, too.
Backing control is not significantly different with the Arrow. I don't know how the Cub might handle.
Finally, my experience with customer service and support from Hensley has been superb in every way. I hope Aaron or someone else there can help you out as a result of a phone call to them.
