I take the stock EVSE out, still in the bubble wrap, and stored them just for the return. A 120 volt only EVSE has near zero value to me in the car.

Get a spare tire for long hauls and put it in a Hefty heavy duty trash bag. The bolt pattern is 4.5" (114.3mm) * 5 lugs. My spare happens to be off a Nissan Altima, 2002 or newer, $15. You will need to modify a junk yard "sciccors jack" (Walmart has them new) so that it doesn't hit the battery. Don't forget the Walmart 4 way lug wrench.

Take the slime / goop Fix-a-Flat out of the car and store it with the EVSE.

Get your road flares, tow strap, jumper cables, winter gloves, and whatever else you keep in a car normally.
