Yes, yes it does look a lot like Copper City. Ha. Went for a bike ride and ended up doing more trail driving, shaking out the truck and camper, than biking that day.
1up racks are very solid with a built in hitch stabilizer ball in the hitch bar. Love them. The one in the image is a 1up Superduty rack. So I had a superduty on a superduty. Ha. I did just get in the 1up xtremduty rack and will be selling the 1up superduty that has served me well for around 5 years. The xtreme duty can handle my wife's Surron LBX (though the Superduty can as well if the battery is removed). The xtreme, and the newest design superduty, are both wide trays, like if you had a fat tire kit on the older 1up racks. The extra width would allow MTB tires to move around more but there is the optional wheel chock that will lock in the front tire, so that more than makes up for it. If I was running only MTB, I'd stick with the narrower/original Superduty or maybe even the slightly lighter build Heavyduty rack which is still the old/narrow style. I built up the new xtremeduty rack and need the rain and snow to stop so I can use it as I want to ensure I like it before selling the 1up superduty (which should sell fast as they are like gold on the used market plus the prices have gotten stupid over the last few years. That will help recoup some of the cost of the xtremeduty).
I've found the Wilco swing out doesn't add much rocking. It also has a built in stabilizer in the hitch bar. Some swing outs don't and with those, you'd just want to use an aftermarket external hitch antirattle device. Getting rid of the tiny bit of receiver slop is key to a stable bike rack. The only movement I get is the bikes in the rack and that is just the nature of the design to have some bike wiggle. All touchpoints are tires only so no worries about cranking down suspension, anything rubbing/touching frame, etc.
