We have a 2017 Yukon currently, and the Model X is not big enough to be a replacement for it. So the plan is for the wife to drive the X and me to drive the Yukon until either my R1S or my Cybertruck arrives. Not holding my breath for either of those though! Lord knows, maybe 2024? 2025?
The R1S is about 10% smaller interior room than our Yukon, but the frunk should help make up for that. I really wish they offered an R1S XL that had the same overall length as the R1T (an extra 18” or so). That way you could have useable space behind the third row. Same thing with the Model X, I wish they offered a long wheelbase edition that added a couple feet in length. It’s not like added length increases drag, and the added weight’s effect on range can be more than offset by a longer, larger battery pack.
