What's the difference between the RTT and RTT XLUpdated 6 days ago

The RTT XL is everything you love about our standard RTT - just 6 inches wider.

That extra width makes all the difference: it’s a perfect match for the Ineos Grenadier, with optional direct-fit mounts for a clean, factory-like install.

It’s also the exact width of our full-size truck topper, so if you want to run your RTT XL on top of your GFC topper, it’ll line up perfectly for a seamless look and aerodynamic fit.
