DIY Foul Weather Charge Port Cover

Ever since I got my R1S, I've noticed that the battery range estimation hasn't been the best. Driving a Tesla for the last 3 years, it never had this kind of issue. During my last trip, the driver display shows 255mi remaining. My total trip (including 2 destinations) is 160mi so I believed I should be able to make it easily with a nice cushion. But the center display showed that I would arrive at first destination with 4mi remaining, and run out before the second destination! I knew this was false so I made the drive anyway, and arrived at second destination with 50mi remaining. If I understand correctly, the driver display range is simply the total rated range multiplied by SOC. That makes sense here, since my vehicle is rated for 370mi, 255mi is 68.9%. Coming from Tesla, I expect the number shown in the center display should account for factors like elevation, wind, traffic speed, etc. It's sad that my own mental estimation is better than Rivian's.

I've seen a couple of posts online and heard a few owners complain recently for Foul Weather charge port covers. Figured I'd share what I came up with a few years ago.

A Styrofoam faucet cover, the flared end of a water bottle and a ratcheting extension cord clip. Cut hole in Styrofoam, insert cut water bottle for added length. Put charge handle inside, plug in vehicle.

Then attach ratchet clip so it dies not move. Works great the few times ive used it. Could probably even use the pull strap that comes with the faucet cover instead of ratchet clip. Covers port, but not door & jamb from ice.

Best solution is if rainy / snow mix expected, don't charge that night. Also suggests wiping liquid silicone on rubber seals in expected foul weather. Especially tailgate/ tonneau seal.

Hope someone finds this information a tad useful.
