2017 Acura RDX. I need to load an 80" long replacement exterior door and jamb into the back and drive home from my local Lowe's. It will stick out of the back of the vehicle by several inches. The tailgate obviously will not close at that point. I want to just tie the tailgate down to where it touches the door frame loaded in the back of the vehicle. Can I drive with it open like that? ...or will the car not start?

 

Doing that in my 2013 worked just fine.

 

yup. No issues, aside from the warning light

 

It works, use the seatbelt to secure.

 

Been there, done that hauling mattresses. Two issues, the alarm chime will be sounding off the entire time you're moving and potentially lethal exhaust can (will?) be drawn into the cabin so roll your other windows down. I do miss the opening rear hatch window of my (replaced by rdx) Toyota Highlander.

Cheers!
