  1. Toyo Open Country AT III EV vs KO3 on 20”

    Thanks all! Decided to go with the KO3s. Favoring off road durability over range.
  2. Toyo Open Country AT III EV vs KO3 on 20”

    In the spring replaced my OEM Scorpions with Toyo Open Country III EV on my quad R1T. Third time out off roading in Colorado I tore the sidewall on two tires. (Middle Fork Swan to Saint John’s in Colorado Summit County). I was aired down to 26 PSI ( I usually run 39-32 PSI). bad luck? Aired...
  3. Sulley R1T Build. Switch Pro 9100, Comma 3x, Frunk 12v Outlets, Cab Outlets, Btech GMRS 50Pro & More

    Finally got around to completing my GMRS radio and antenna install. Details are here. Pretty happy with the finished product: GMRS head unit was mounted in the passenger side dash, so nicely out of sight.
  4. Sulley R1T Build. Switch Pro 9100, Comma 3x, Frunk 12v Outlets, Cab Outlets, Btech GMRS 50Pro & More

    Thanks for sharing the example tow hook option! I also thought about the ditch light mount option that others have posted. In the end decided to go with the nmo mount on the bed rail cap -- will share how that turns out.
  5. Sulley R1T Build. Switch Pro 9100, Comma 3x, Frunk 12v Outlets, Cab Outlets, Btech GMRS 50Pro & More

    Good question. Hadn't given that too much thought. It is already higher than probably most water crossings I'd attempt. The SP-9100’s power-module is built to the IP 67 standard, so it should survive being under clean, fresh water to a depth of ā‰ˆ1 m (3.3 ft) for up to 30 minutes without water...

    Here is an update on my build with the Switch Pro: https://www.rivianforums.com/forum/threads/sulley-build.47398/
  7. Sulley R1T Build. Switch Pro 9100, Comma 3x, Frunk 12v Outlets, Cab Outlets, Btech GMRS 50Pro & More

    Here is my live google doc writeup. Thanks to everyone who has shared their mods online, it made it immensely easy to tackle my own mods. Sulley R1T Mods Added MegaWatt rock slides. Have definitely made use of the rock slider and the kick-out on some Colorado off road trails. Installed Toyo...
  8. In search for a true ignition 12v trigger

    The Switch Pro is essentially a relay. Main power for devices is straight off the 12v battery. The lead off the marker light connects to a trigger/sensor connection on the Switch Pro and the Switch Pro pulls a couple mA at most. I plan to throw a 1 Amp fuse on the trigger input just to be safe...
  9. How to access amber marker lights on the wheel well?

    Nothing crazy yet. I’ve got multiple 12v outlets in the frunk and cab that I’ve added that I will move over to power off the switch pro instead of a fuse tap. I’m installing a GMRS 50watt radio that I’m going to power off it. I’ve also added some usb-c pd ports with Powerwerx device that I’ll...
  10. In search for a true ignition 12v trigger

    I'm going to use the amber marker light on the front wheel well as an ignition trigger. It doesn't come on when the truck wakes or unlocks. It first comes on when I press the break. The only time it doesn't look like it comes on is if you have the headlights/running lights/et al completely...
  11. How to access amber marker lights on the wheel well?

    Anyone know how to pop the amber marker lights on the front wheel wells off or otherwise access the wires to these lights? I’m installing a Switch Pro and it looks like this would be a good trigger for IGN/Go/Ready. As long as the light setting isn’t fully off, these lights come on when you hit...
  12. Anyone using Rivian (unofficial) integration with Home Assistant?

    I started playing around with this using Influxdb (FLUX) and Grafana. I've got two dashboards - a status focused dashboard (Status Dashboard Code) and a stats focused dashboard (Stats Dashboard). Some notes on this: Edit the vehicleName dashboard for the name (entity prefix) for your vehicle...
  13. Hitch Mounted Spare Tire Carrier

    @Mcscoots, how long of an extension does RambleSwing add? I’m wondering if I can drop the tailgate with 1up rack attached.
