For your situation, I highkey recommend looking into a more structural solution because those vents really aren't designed for load-bearing. From a safety perspective, you want something that won't become a projectile if you're hitting washboard roads. I've been super satisfied with the Course Motorsports Direct Fit Phone Mount for Rivian R1T/R1S.

It's a CNC-cut bracket that actually bolts behind the dash trim—it sounds scary but it's basically a 5-minute install and it's rock solid. No vibration at all during off-roading. I paired mine with a ProClip USA Heavy Duty Ball Mount to get the angle exactly right without blocking the main screen. It keeps the phone right in your line of sight for Waze but feels like a factory part. Honestly, don't risk the wood trim with adhesive or the flimsy vents... this setup is way more secure and looks professional tho. gl with the new truck!

yo congrats on the truck! tbh, i've been using the EveryAmp Dash Mount for Rivian R1T for a bit now and it basically solves everything ur worried about. i'm kinda new to the whole off-roading scene but it stays REALLY steady. i paired it with the Peak Design Mobile MagSafe Car Mount and it looks super clean. it doesn't block the screen at all, which is huge! gl!

Sooo I went through this exact same struggle last year after I picked up my R1T. Honestly, I’m super cautious about anything that might clip onto those slim vents because the mechanism in there feels a bit delicate, you know? Plus, I spent a lot of time on bumpy washboard roads and I’ve seen way too many "secure" mounts just fly off the second things get rough.

I tried a few different things and learned some lessons the hard way:
* Vent clips are a no-go for me because they block the airflow and feel like they might snap the plastic fins if you hit a big pothole.
* Suction cups on the wood dash... yeah, don't even try that. I was terrified it would leave a ring or mess up the finish.
* Simple adhesive mounts usually fail the first time the cabin gets really hot in the sun.

Basically, I eventually found a setup that uses a bolt-on attachment point behind the screen. It was a bit more work to install than a simple clip, but the peace of mind is worth it. It’s rock solid and doesn't vibrate at ALL, even when I'm airing down for some serious trails. Over the years I've realized that if you're actually gonna take these trucks off-pavement, you gotta go with something that physically screws into the dash structure. It’s definitely a more conservative approach but it keeps my phone exactly where I need it for Waze without blocking the main UI. I mean, it’s not perfect, but it’s the most professional looking solution I’ve found so far. gl with the search!

Sooo +1 to what was said earlier about keeping it steady. I totally agree that the vents in the R1T are way too flimsy for a heavy phone, especially if ur planning to hit any trails. I saw this thread earlier and wanted to chime in with a more budget-friendly approach that still looks high-quality.

Ngl, I didn't wanna drop $100+ on a mount setup, so I went with the BestEvMod Lower Center Console Phone Mount for Rivian R1T. It's super solid because it bolts into existing spots so there's zero vibration. I paired it with a cheap but strong ESR Magnetic Wireless Car Charger with CryoBoost and honestly, it's been perfect.

* Total cost was like half of the high-end boutique brands
* Keeps the wood dash completely clean
* Super easy to see Waze without blocking the main screen

I've been using it for months and I'm really happy with how it holds up on washboard roads. Definitely a solid way to go if you want that clean look without breaking the bank! 👍

Yep been there done that. Can confirm everything said above is spot on.
