Having loved my Db cover for last 2 years, I, too, was looking at racks and the reviews were...less than enthusiastic. For what it's worth, I went another way and have been thankful every day. If interest I can provide more details.
I
almost went with
this but wasn't 100% sold it would exactly fit my Gladiator. They were very helpful over the phone so maybe you could work something out.
I then watched
this video a few hundred times and connected with Greg at PakRax. Super sturdy, gas struts still open each wing fully with lots of room for inflatable kayaks, SUP, etc. under the RTT I'll mount on them.
