As a newb in off-roading, there are several things I would like to suggest.
1) Winch mount - there's a frunk, you can set a winch mount somewhere.
2) Standard suspension assembly - in case buyers want to upgrade suspension to higher grade suspension or lift.
3) Mount points for rock sliders -...
If this is to be a fun, outdoor, off-roading SUV, an open back section would be nice option (I think). It will be like the 4Runners of the past (and some back country fabrications).
I guess it's not an option because the market research says it's not profitable. If not, at least make it easy...
