Largest Rhino-Rack Pioneer Platform Tray for Use With Retrax Tonneau Cover

Question:

I have a retrax bed cover on my 2021 GMC Sierra. I’m looking to fit the biggest Rhino Rack Pioneer platform over the bed cover. It has built in t-slots on both sides of the bed rail. The 72x56 size is good but I’m not sure how to mount it. Can I mount the rack to cross bars? Can you help me achieve this task?

There are several different sizes of the Rhino-Rack Pioneer Platform Racks but the vast majority of these won't work as they don't mount to standard crossbars and that's how you'll have to attach one using the tracks on a Retrax Tonneau Cover. The largest option for standard crossbars is the Rhino-Rack Universal Pioneer Platform Rack part # RR42115BF which measures 58" long x 47" wide. If you don't already have crossbars I recommend the Rhino-Rack Vortex Crossbar System for Retrax XR Series and Mountain Top EVO-M Tonneau Covers part # RRVA180B-RRRLT600.
