I haven't used the curt hitch with the kuat sherpa, but I have with the Swagman Chinook and it works great.

 

I don't have the Kuat, but have a Yakima Holdup +2 (4 bikes total) with the Curt 13427, and it works just fine. Just enough clearance to the bumper, and enough height for reasonable clearance at the back.

The only item of warning that I would provide with tray racks is that during a heavy bump (think speed bump too fast), there is a significant risk that a mountain bike handle bar could strike the rear window when the rack bounces up. I personally experienced this, and luckily the rear window did not break, but the impact was very loud. The next long trip we take with bikes will involve some sort of padding on the end of the front most handle bars. I'm thinking a chunk of pool noodle with duct tape and a zip tie or similar...

Also be aware that a 4-bike tray rack is very long, if you intend to do any off-roading with bikes loaded, consider a hanging type of rack for less rearward extension and ground clearance.

 

Thanks for the feedback! My main concern was having enough clearance between the rack and the car when its in the stowed position. I like the Curt 13427 because you only see the receiver, not the entire hitch frame. Has a nice clean look. I appreciate everyone's help!

 

I'll probably have the rack back on the car this weekend and loaded up. I'll try to remember to take a photo showing clearance while stowed.

 

I've got a Rocky Mounts on a Draw Tite mounted to a 2021 Calligraphy. No problems with clearance. It's great because it can fold up or down.
