I'm not a big fan of DEI. I think we should all be treated equally, regardless of race, gender, ethnicity or the presence or absence of mental illness, not one group getting special treatment or privileges.
Uh, oh. Don't let @The Green Goat know I said that!
Yes you can run both. DEI's stuff goes behind the plastics. Mine installs behind the seats and above the plastics. Way easier to install and is a full blanket.
