There is a post on Trailrivian about a bumper protector that looks pretty good, but I thought it'd be nice to have another option just in case. So I came across a Jeep owner who kludged together this rear end/bumper protector for his new ride.
The Pintle mount shank is 2" X 10" long solid steel and the plate is 3/8" thick solid steel. The piece weighs 16lbs by itself and is rated for 13,000LBS. The bumpers are solid rubber 2.25" thick and 7" long. Luckily, the two holes in the bumpers lined up with two holes in the mounting plate, so no drilling or modifications to the bumpers or plate were needed.
Holding the bumpers to the plate, he used four brass machine screws 1/4"x2.5" long with SS fender washers on the bumper side and 5/16" + 1/4" washers stacked on the mount plate side with a lock nut setup to prevent them from coming loose. The hardware he used costs about $10 total and was picked up at HD.
He needed the 10" long version of the Pintle mount because he wanted it to be at least flush with his spare tire on his Jeep, which, by the photos, you can see it is. Since Rivian doesn't have a rear-mounted spare tire option, I believe you could use the 9" version of the mount so it won't nail anyone's shins if they pass too close to your vehicle.
FWIW- he went with the "Save With Used" version of the mount because it was $10 less than the new version, and it was still in new condition, just repackaged by Amazon due to weighing so much and busting up its original shipping carton. If I can recall correctly, I think the "Save With Used" 9" mount is only $27!
Of course, in a very hard rear-end hit, this might not do too much (and nothing will), but if someone creeps up/rolls into it at a stoplight or while backing up in a parking lot, it might just save you from replacing your rear bumper & bumper cover, which might cost a lot to replace.
