This is what I usually store in the rear bumper:
shackle draw bar
4" drop draw bar with 2" ball
bottle jack
bolt cutters
various draw bars
hammer
tire chocks
cribbing
fluid transfer pump
10,000# snatch block
screw-in tree cleats
tree saver strap
20' chain
10'chain
3' chain
axe
machete
come-along
trailer connector adapters
various bars & bolts
whatever else I can stuff in there...

.

That latch never worked right, so eventually, it went away.

This bumper ended up weighing ~180# empty (when it was on the '83 frame).
