This could be a fun game.
I usually carry gear oil, engine oil, grease, grease gun, water, coolant, 1/2" socket set, 3/8", metric spanners, ratchet spanners, imperial spanners, screwdrivers, breaker bar, assorted pry bars, set of various pliers, few spare nuts, bolts and bulbs, and a shit load of cable ties. If I didn't I bet it'd break instantly.
I don't have locks on my doors so nobody rob me please.
