Knocking Noise From Right/Rear of my Rivian Cabin

A friend needed to support his son who would be running a 'very cold' marathon on Sunday while rucking a 30 pound pack. The outside temps will be around 15F-20F the whole time. The location of the race is nowhere close to any L2 chargers, but he's not worried about driving distance to or from the race - it is 50 miles away from his house. He says he will be sitting in his ruck with his laptop and watching his live track+Garmin inReach data for the duration of the race (about 4 hours). He thought about taking his Honda EB2800i gasoline powered generator, if he can use the level 1 EVSE attached to the generator and keep the truck running with full heat + power - without really consuming much of the truck's main battery? He feels it's super dorky to have a gas generator running while attached to a Rivian in the woods, just so he can stay warm, but don't know if it would work ok this way and 'preserve' the main battery so he doesn't need to worry about driving range when we wants to head home. He talked to me about it and I told him the simple answer is NO. I tested this theory the other night when I was plugged into a 5.9kW charger. To maintain the interior amenities (interior and exterior lights, radio, heater, seat heaters), it took almost all of the charge. I charged for 15 minutes, it delivered 1.6kW, and the truck consumed 1.4kW, delivering only 0.2kW to the truck battery. Told him he would be using a laptop at another 200ish watts. The little trickle charger charges at 1.4kW on a good day, 1.2kW is normal for me. You can slow the bleed, but you cant stop it. My advise to him was for him to charge it up to 100% at home, and roll the dice is what I would do.

Anyone else have a knocking noise from the right or left rear of cabin? I took it to the service center and while the tech heard it on our drive, he was unable to make it re-appear after he "moved some things around". Translation: Didn't do much to address it.

I'm really bothered by the fact that the service centers don't have harsh enough rosds to test these vehicles on. I live on a dirt road. This noise is new and not only loud & annoying, but worrisome. Service rep said, the truck needs to break in. Ha! It's breaking all right.

I'm pretty close to disassembling the rear interior myself. A 2.5 hour drive to the service center with a crappy Enterprise loaner, just have have them give me the runaround is not fun prospect.
