Yes.
Without those ports blocked, it pressurizes the area between the tannau and the RTT. This actually causes the cover to inflate like a balloon lol, not the most efficient use of airflow.

It depends on what you're routing the air over lol. But generally speaking, if you're towing or have a load, you're probably looking at roughly 3%, as well as not "pressurizing" your load lol.
If nobody has gotten you pictures of that when I'm done with this trip, I will take pictures for you with the tape off.
Closeouts for this area would benefit anybody with an RTT, or towing for that matter.
Seriously, the Rivian mobile charger is junk. Use the one you got for free, but never buy one.
The unit has zero line test ability, errors out at the slightest problem (simply does not work in Mexico) and is made with the cheapest Chinese parts.
Have you ever seen cheaper plastic than the thin...
The Rivian portable charger is junk. Virtually every portable charger made in China that you can get on Amazon is junk. Use it your own risk.
I highly recommend Tesla, or Clipper Creek, for a quality portable charger. The advantage of the Tesla is that you can augment it with the NEMA kit, and...
Yes, it is an ecoflow 2, and yes, its efficiency drops pretty dramatically at about 40°.
I also have a small low draw quartz radiant heater that I use to boost temps in the tent if I am going to be camping in the very cold, but for the most part, the eco flow does great.
Add it's ability to...
Lol
It's a truck, and it got Oregon pinstriping down both sides the first week I had it from being in the woods. I am definitely a function over form guy, so the marks from aero covers don't bother me, neither will the marks from an aero block out.
That said, mark's left by roof block outs...
Even the tiny little mud guards for the Model 3s have a noticeable impact on efficiency and range.
The airflow around the tires is a particularly important piece of the overall aerodynamics of the vehicle. Any alteration in that area will typically cause efficiency drops.
As a general rule, always air down off road.
How much is highly dependent on the wheels and tires you are running. The combination of a heavy vehicle and limited sidewall with the R1 severely limits the amount you can air down even with good tires and wheels. Where I run 8 to 12 lb in my TJ, I...
Oh... I should mention. If I spent all of my time in Baja sand, I would absolutely go with a QM.
So at the end of the day, it really is how you intend to use the vehicle.
