I have the Kuat rack with the Kuat Pivot, highly recommend!! I love the Pivot because it extends the rack past the 5th wheel and pivots out of the way for access to the tailgate. You can get the Pivot in right or left swing. I went with right swing so bikes can stay off the road when everything is opened up.
One up is the way to go. It is very serviceable and easy to replace parts as they wear out. Had mine for 3 years with no issues. Warranty is superb as one of the bolts came loose and was lost somewhere. Contacted them for a replacement and they sent me a few at no cost. I had to purchase the hitch extension to clear the spare on my Badlands non sas. Worked great.
Receiver: Curt3
Extender: Kuat Pivot, drivers side swing
Rack: 1Up, Heavy Duty, double, black
Tailgate table - @IAG Off-Road drop down table complete my set up area and is super helpful for staging gear (gloves, helmet, etc) or tools (chain oil, wrenches, etc)
I also hathe 1Up modular platform tray that I can add to the rack for extra storage (luggage, cooler, etc)
We bike several times a week and this set up has been great
I chose the Quikr over 1-up for a couple of reasons. First reason is the fact the it can accommodate up to 5" tire as delivered and the second reason is the ease of adding/removing additional racks without tools. I use the rack with the Kuat pivot for swing away. Having said that, Quikr does cost more.
