Sooo, I actually just joined the R1T club myself last month, but honestly, I've spent years obsessing over interior safety specs in my other rigs. I once had a scary moment where a loose mat bunched up under my brake pedal during a steep descent, so I’m super picky about anchoring now. For your situation, I’d suggest checking out TuxMat Floor Mats for Rivian R1T. They provide insane edge-to-edge coverage and use these specialized clips that lock into the side panels, so they literally won't budge even if you’re bouncing over rocks. Here’s what I’m using for the rest:
* WeatherTech Cargo Liner for Rivian R1T for the frunk—it’s super easy to hose off.
* BestEvMod Gear Tunnel Mat for Rivian R1T because it handles heavy hiking boots without scuffing. One technical thing... make sure the mats dont block those rear vents. Proper airflow is key for the HVAC system’s efficiency. Stay safe out there! 👍

Seconding the recommendation above! Honestly, I've been running the 3D MAXpider KAGU Series All-Weather Floor Mats in my Quad-Motor since launch and they're basically bulletproof. One technical detail people miss is that patented MAXpider backing—it grips the carpet like crazy, so they *definitely* wont move even when you're hitting technical trails or high-speed washboard roads. If you're worried about the rear vents, the fitment is precise enough that it doesnt block the flow, but the raised edge is high enough to catch spilled coffee or melted snow before it drains into the ducting. For the frunk and tunnel though, I actually went a different route. I'm super satisfied with the LinerX Rivian R1T Frunk and Gear Tunnel Mat Set. Tbh, the TPE material they use is slightly more 'grippy' than the MAXpiders, which is great cuz it stops my hiking gear from sliding around during hard regen braking. They're super easy to spray down at the self-wash too. Definiately worth the investment for the total coverage. gl!

In my experience, I've been driving my R1T through two brutal mountain winters now, so I definitely get the struggle with factory carpets getting trashed. After testing a few setups for durability, here is what I recommend for total edge-to-edge protection: * Get the 3D MAXpider KAGU Series All-Weather Floor Mats for Rivian R1T for the main cabin. The fitment around the rear floor vents is precise, and honestly, that 'MAXpider' fiber backing keeps them anchored during off-road bumps way better than traditional clips do. * For the storage areas, the Rivian R1T Official All-Weather Frunk and Gear Tunnel Mat Set is actually superior. They’re heavy-duty TPE and basically indestructible when you're tossing muddy hiking gear inside. Lesson learned: the custom-fit stuff is 100% worth it to prevent moisture seepage under the edges and keep the floorboards pristine... seriously!! gl with the new truck! 👍

Curious about one thing: what’s your total budget for the cabin, frunk, and tunnel? Asking cuz in my experience, I’ve tried many liners over the years and the one I got was way cheaper than the big names. Technically it has the same density specs and fits the vents perfectly during off-roading!! I reallyyy learned you don’t always gotta pay for a name to get edge-to-edge protection. What’s the max you wanna spend??

Same here!
