Adjustable 68.8" Truck Bed Rack Cross Bars (2PCS), Heavy-Duty Aluminum T-Slot Crossbars Compatible with Mid-Size Trucks & Retractable Tonneau Covers with Rail System, Kayak & Bike Rack

The rack is a budget option that doesn't seem to be available. If I could do it again, I'd do the low profile Realtruck Elevate Base Rack, but this is the one I did. https://www.amazon.com/dp/B0FQ61X7BX The RTT is a Naturnest Sirius 2 ABS. They have a few versions and a few sizes, but they're pretty affordable, especially if you're dipping your toes into it. https://www.naturnest.com/products/naturnest-sirius-2-clamshell-rooftop-tent Pretty sure I got both for less than 2k total on deals so it was a great way to get started.
