>>1801690get a rack
zip tie a big metal basket on it
just very useful generally for groceries etc.
tripod could just be on an angle and strapped down poking out of the rack if the basket is too small for it.
you could also get a length of pvc pipe, like a big culvert one, and attach it vertically on the side of a rack to put tall things in more easily. Cut some small notches around to zip tie it on, or use u-clamps. You could run it flush to the bottom of the top basket and cut a hole in the basket for it.
