I used one once on my Tacoma (I bought it for a specific event and haven't had an opportunity to use it again). It worked fine, but we didn't experience any rain or adverse weather. Admittedly, its more work to set up (especially in poor weather). Other than that I'm not sure what the major advantages of a roof/bed top tent (except that you don't lose your bed storage.
Comparing the Rivian's bed dimensions to the tacoma (short bed):
Width: 51.1" (Rivian) vs 52.5" (Tacoma)
Lenght (tailgate up): 54.1" (Rivian) vs 60.5" (Tacoma)
Length (tailgate down): 83.9" (Rivian) vs 80" (Tacoma)
Height : 18.3" (Rivian) vs 19" (Tacoma)
I haven't taken these measurements myself but found them on the 'net but it gives you an idea. They measure pretty close except for the open bed. The same tent you use for the tacoma might work on the rivian. I just can't remember if there is enough give to accommodate the extra 3".
If you can wait until the third quarter of 2023 (when I'm scheduled to get my Rivian), I'll let you know.
Otherwise, wait until ridgeline makes one specific to the Rivian which they totally should. It would be an awesome alternate.
