I have a 6t bottlejack from Harbor Freight. It fits (standing up) in a Homer toolbox from Home Depot, along with some 2x8's to use as blocking. I think there is 4 or 5 2x8's the length of both of the two seen on top, with a 45* cut at one end in the long ones to drive the good tire up on.
Threw a reflective vest that work handed out this last safety kick off in there and also have a paint suit (not seen, keeps jack in place) to wear on if needed.
I have these led safety puck light flares
for the just in case. Bought mine at Autozone on sale for $15, worth it Imo. Also carry a collapsible cone with an led light in it that work gave us.
