Good point, definitely could go either way or even not at all. Just basing my comment on what we have heard to date which was that it could be purchased and installed at SC and takes about 1/3 of bed. Seems like something you would have installed after the fact because of the SC install versus...
You purchase separately after the fact so the tax credit still applies to original purchase, but tough comparison since in this situation you actually lose a lot of bed storage whereas the Rivian is integrated. Then again, having the option later is a plus.
